Abstract :

In this work, we systematically investigated the hardness, electrical resistance and thermal stability of nanocrystalline NbMoTaW high entropy alloy films with thickness varying from about 100 to 2000 nm. The nanocrystalline high entropy alloy film exhibited the peak hardness (similar to 16.0 GPa), strong size-independent electrical resistance (similar to 170 mu Omega.cm) as well as stabilized single phase body-centered cubic (BCC) structure even after exposed to vacuum annealing at 800 degrees C for 2 h. In the meantime, we provide reasonable insights into understanding behaviors above. With superior mechanical and electrical properties as well as good thermal stability, this kind of refractory nanocrystalline HEAFs will find extensive potential applications. (C) 2017 Elsevier B.V.

Abstract :

The size-dependent hardness, strain-rate sensitivity (SRS) and shear transformation zone (STZ) volume of co-sputtered Cu-Zr metallic glass films with film thickness h spanning from 1000 to 3000 nm were systematically investigated by nanoindentation creep tests at room temperature. Experimental results manifested an exceptional decrease in hardness and a monotonic increment in SRS (or a monotonic decline in STZ volume) with reducing h. The deformation mechanism could be rationalized in light of more free volume combined with smaller STZs in thinner films, which likely trigger the strain-softening behavior. Moreover, STZs and deformation-induced devitrification promote the homogeneous-like plastic flow. IMPACT STATEMENT Employing nanoindentation creep tests revealed size-dependent hardness and strain-rate sensitivity in metallic glass films, enabling comprehensive understanding of the deformation mechanism based on atomic-scale shear transformation zone theory.

Abstract :

The buckling strain epsilon(B) of Cr films and Cu films exhibits opposite film thickness h dependence: the CB of Cr films decreases monotonically, while the epsilon(B) of Cu films increases monotonically with the increasing h. The delamination of Cr films follows the strain energy criterion while the Cu films are buckle-limited. The epsilon(B) of Cu/Cr nano structured metallic multilayers (NMMs), much higher than that of Cr films, increases as the modulation period lambda increases. A modified strain energy criterion involving interfacial adhesion and plastic deformation has been developed to describe the evolution of epsilon(B) of Cu/Cr NMMs with lambda.

Abstract :

Here we report the effects of Zr addition (0.1-0.3 at.%) on the multi-scale second-phase particles and fracture behavior for Mg-3Gd-1Zn (at.%) alloys. Microstructural features of the alloys in the as-cast, solutionized, and aged conditions have been investigated in detail. The results have revealed that the cast alloys are mainly composed of alpha-Mg matrix, eutectic phase (Mg, Zn)(3)Gd, 14H long period stacking ordered (LPSO) structure and cuboid shaped GdH2 phase. After solution heat treatment, the eutectic phase (Mg, Zn)(3)Gd has transformed to X phase with 14H-LPSO structure, which has different distributions and morphologies due to different Zr additions. When the Zr addition is 0.3 at.%, a large amount of microscale Mg(Gd, Zn, Zr) particles appear along the grain boundaries. After aging heat treatment, Mg-3Gd-1Zn alloy with basal precipitates gamma '' exhibits poor age-strengthening response. In contrast, Zr addition to the Mg-3Gd-1Zn alloy gave rise to a strong age-strengthening response. The strength improved significantly due to dense distribution of nanoscale prismatic plate beta' and beta(1) precipitates, which are not observed in the Zr-free alloys. One key finding of this study is that Zr contributes to formation of the prismatic precipitates, and their amount increase with increase of Zr addition. The mechanical damage for these alloys is a sequence of microscale GdH2 or Mg (Gd, Zn, Zr) particles cracking, followed by fracture of the surrounding particles, and finally the growth/coalescence of micronvoids in the alpha-Mg matrix. The fracture of microscale particles was quantitatively analyzed by a Weibull model. (C) 2018 Elsevier B.V. All rights reserved.

Abstract :

Al-XCu (X = 1.0, 1.5, and 2.5 wt%) alloys with and without 0.3 wt% Sc addition were prepared respectively. The effects of composition and heat treatment processes on the microstructural evolution were systematically investigated by using transmission electron microscope and atom probe tomography (APT). Both Al3Sc dispersoids and theta'-Al2Cu precipitates coexisted after artificial aging, and a strong Sc segregation at theta'-Al2Cu/matrix interfaces was detected and quantified through APT examinations. A Sc solute partitioning was demonstrated between in the Al3Sc dispersoids and at the theta'-Al2Cu/matrix interfaces, mediated by the Cu content. Increasing the Cu content, both the size and volume fraction of the Al3Sc decreased after solid solution treatment. As a result, the interfacial Sc segregation was accordingly intensified during subsequent aging treatment. A parameter of reduction in interfacial energy (Delta gamma), derived from APT analyses, was proposed to characterize the degree of interfacial Sc segregation. The coupling effect of Al3Sc dispersoids and theta'-Al2Cu precipitates on ductile fracture was discussed, where a micromechanical model was developed to describe a quantitative relationship between the fracture strain with Delta gamma as well as parameters of the Al3Sc dispersoids.

Abstract :

The effect of precipitates on fracture behaviors was comparatively investigated among three kinds of Mg alloys with different precipitates, i.e., Mg-Gd alloy with prismatic plate-shaped precipitates, Mg-Zn alloy with [0001](alpha) rod-shaped precipitates, and Mg-Gd-Zn-Zr alloy with basal plate-shaped precipitates. By comparing the fracture behaviors of the alloys before and after aging treatment, it was evident that the presence of precipitates greatly promoted the formation of microvoids that were initiated at primary intermetallic particles. Voiding was the most accelerated in the Mg-Gd alloy, where the precipitate-dislocation interactions are the strongest. While in the Mg-Gd-Zn-Zr alloy with the weakest precipitate hardening, the precipitate-facilitated voiding was the least significant. The precipitate-dependent voiding suppressed the twinning behaviors, causing the volume fraction of deformation twins decreased in turn from Mg-Gd-Zn-Zr to Mg-Zn, and finally to Mg-Gd alloys. The tensile ductility of present Mg alloys approximately scaled with the volume fraction of deformation twins, and was highly sensitive to the precipitates. The fracture scenario of present Mg alloys was proposed that the voiding suppressed twinning and the competition between voiding and twinning can be mediated by precipitates. In the Mg-Gd-Zn-Zr alloy with limited voiding, the twinning dominated the deformation process and concomitantly resulted in a great ductility. The formation of microvoids or the fracture of primary intermetallic particles was quantitatively analyzed by applying a Weibull model, where both the alloy strength and the volume fraction of primary intermetallic particles were considered to rationalize the remarkable difference in fracture behaviors among the present three Mg alloys. Furthermore, the coupling contribution of precipitates and twins to the work hardening was modelled in the aged Mg-Gd-Zn-Zr alloy that displayed a large room temperature tensile ductility of similar to 13.5%.

Abstract :

Tuning the microstructure to optimize the mechanical performance of nanocrystalline Cu thin films via the alloying strategy is quite important for their application in microdevices. In this work, we prepared nanocrystalline miscible Cu-Ti and immiscible Cu-Mo alloyed thin films to investigate alloying effects on the microstructure and mechanical properties of Cu thin films in terms of mixing enthalpies. It is found that the dopants of both Ti and Mo can notably refine the grains, and in particular promote the formation of nanotwins below a critical content of solute, beyond which the formation of nanotwins is notably suppressed. The nonmonotonic solute concentration-dependent twinning behavior observed in Cu-Ti and Cu-Mo alloyed thin films is explained by the coupling effects between grain size and grain boundary segregated dopants that affects the stimulated slip process of partials. The increased hardness of both Cu-Ti and Cu-Mo systems with increasing the solute contents are quantitatively explained by combining several strengthening mechanisms, including solid solution strengthening, grain/twin boundary (GB/TB) strengthening, solute segregation-induced strengthening. It unexpectedly appears that with increasing the solute contents, the Cu-Ti system exhibits monotonically reduced positive strain rate sensitivity (SRS, m), whereas the Cu-Mo system manifests almost constant negative SRS. The fundamental difference in SRS m between Cu-Ti and Cu-Mo is rationalized in terms of the interactions between solute atomic clusters and dislocations based on the cross-core diffusion mechanism.

Abstract&Keyword Cite

Abstract :

Coarse-grained (CG), fine-grained (FG), and ultrafine-grained (UFG) Al-2.5 wt% Cu (Al-Cu) alloys were respectively prepared, with and without 0.3 wt% Sc addition, for comparison. The influences of minor Sc addition on the microstructural evolution, tensile mechanical properties and pitting corrosion resistance were system. atically studied at different grain scales. A significant Sc microalloying effect on the precipitation was observed that the minor Sc addition promoted the dispersion of finer theta'-Al2Cu precipitates in the CG alloy and favored the intragranular theta'-Al2Cu precipitation in the FG and UFG alloys, with the smaller grain size leading to a stronger Sc microalloying effect. The Sc addition induced convincing increases in the yield strength at all the three grain scales, and improved (in the CG and UFG Al-Cu alloys) or retained (in the FG Al-Cu alloy) the pitting corrosion resistance at the same time. This indicates that the inverse strength-pitting corrosion correlation as usually observed can be broken by minor Sc addition. The strengthening mechanisms were discussed and the grain size dependent pitting corrosion resistance mediated by the Sc addition was rationalized in terms of a competition between the positive influence derived from the interfacial Sc segregation and the negative influence come from the deformation-induced dislocations. The present findings provide a possible approach to break the inverse strength-pitting resistance correlation in heat-treatable Al alloys by modifying the precipitate/matrix interfaces through the suitable microalloying atom segregation.

Abstract :

In order to achieve desired mechanical properties of alloys by manipulating grain boundaries (GBs) via solute decoration, it is of great significance to understand the underlying mechanisms of microstructural evolution and plastic deformation. In this work, nanocrystalline (NC) Cu-W alloyed films with W concentrations spanning from 0 to 40 at% were prepared by using magnetron sputtering. Thermal stability (within the temperature range of 200 degrees C-600 degrees C) and hardness of the films were investigated by using the x-ray diffraction, transmission electron microscope (TEM) and nanoindentation, respectively. The NC pure Cu film exhibited substantial grain growth upon all annealing temperatures. The Cu-W alloyed films, however, displayed distinct microstructural evolution that depended not only on the W concentration but also on the annealing temperature. At a low temperature of 200 degrees C, all the Cu-W alloyed films were highly stable, with unconspicuous change in grain sizes. At high temperatures of 400 degrees C and 600 degrees C, the microstructural evolution was greatly controlled by the W concentrations. The Cu-W films with low W concentration manifested abnormal grain growth (AGG), while the ones with high W concentrations showed phase separation. TEM observations unveiled that the AGG in the Cu-W alloyed thin films was rationalized by GB migration. Nanoindentation results showed that, although the hardness of both the as-deposited and annealed Cu-W alloyed thin films monotonically increased with W concentrations, a transition from annealing hardening to annealing softening was interestingly observed at the critical W addition of similar to 25 at%. It was further revealed that an enhanced GB segregation associated with detwinning was responsible for the annealing hardening, while a reduced solid solution hardening for the annealing softening.

Abstract :

Grain boundary (GB) engineering via alloying opens a pathway to design the interfaces in alloys for tuning their mechanical properties, thus it is quite critical to determine the optimum addition of alloying element. Here, we prepared immiscible Cu-Cr alloyed thin films by non-equilibrium magnetron sputtering deposition to study Cr alloying effects on the microstructure and mechanical properties of Cu thin films. It is found that Cr doping can notably refine the grains and promote the formation of fully nanotwinned columnar grains at low Cr volume concentrations (<=similar to 3.7 at.%) associated with the average GB Cr concentrations <=similar to 15 at.%, beyond which the formation of nanotwins is significantly suppressed. The role of Cr atoms/clusters played in the twinning process is rationalized in terms of dislocation rebound-promotion mechanism. Importantly, a maximum hardness is discovered at the optimum Cr addition of similar to 2.0 at.%. The Cr concentration-dependent hardness of Cu-Cr alloyed films was quantified by a combined strengthening model. The achievement of the maximum hardness was related to the greatest GB solute segregation-induced strength contribution. It is further uncovered that the Cu-Cr system exhibits strain rate sensitivity (SRS, m) monotonically reduced with increasing the Cr concentration, ranging from a positive m of 0.0314 (for pure Cu) to a negative m of -0.0245, which is attributed to a competition between the dislocation-boundary interactions (increasing m) and the dislocation-solute atoms interactions (decreasing m). These findings provide valuable insights into tuning the composition of alloyed thin films to achieve optimized mechanical performance. (C) 2018 Acta Materialia Inc. Published by Elsevier Ltd.
