Abstract :

Effect of milling time on the microstructure and mechanical properties of Ti(C,N)-304 stainless steel cermet and the fracture mechanism were studied in this work. The microstructure was investigated by means of x-ray diffraction (XRD), scanning electron microscope (SEM) combined with energy dispersive spectrometer (EDS), and field emission transmission electron microscope (FETEM). FETEM and EDS were also used to analyze the Ti(C,N)/304ss interface. Mechanical properties such as transverse rupture strength (TRS) and hardness were also measured. Results show that prolonged milling time decreases the Ti(C,N) grain size and improves the homogeneity of microstructure. As a consequence, the frequency of intergranular fracture increased and it can improve the mechanical properties. Fe and Ti elements could interdiffuse and the hard phase was closely bonded with binder phase. The Ti(C,N)/Ti(C,N) interface was weaker than Ti(C,N)/304ss interface. Results also show that the transverse rupture strength and the hardness increase with increasing milling time and the maximum values were obtained at 18 h with 1437 MPa and 83.7 HRA, respectively.

Abstract :

In this paper, Fe, Ni, Cr, Mn, Si, Celement powders and Ti(C,N) ceramic powder were used as starting materials to fabricate Ti(C,N)-304 stainless steel cermet via high-energy ball milling in argon atmosphere. Effect of milling time on powders' structure, including morphology of powder, average grain size, dislocation density and the solid solubility of Cr in Fe, were studied by x-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). XRD pattern shows that mechanical alloying was occurred during high energy ball milling. Nickel and chromium were gradually solid dissolved into iron and formed 304 stainless steel (304 s), the maximum solid solubility of Cr in Fe is 16.8 at.% obtained at 18 h. The mean grain size of Ti(C,N) particles and 304 s grains declined before 14 h and the minimum grain size of them were about 20 nm and 250 nm respectively, which is consistent with the results revealed by TEM images. The dislocation density in stainless steel powder increased with increasing milling time. After the powders were milled for 18 h, the cermet sintered at 1450 degrees C for 1 h has the maximum hardness (83.7 HRA) and relative density (93.3%).

Abstract :

In this paper, in-situ submicron TiB2 particles (2.5 wt.%) reinforced AZ91 matrix composites are processed by the master alloy method combined with an optimized SHS technique. The effect of TiB2 particles on the microstructure, ageing behavior and mechanical properties of Mg matrix composites is investigated. The results reveal that only TiB2 phase is in-situ formed in the Al-TiB2 master alloy and exhibits the size distribution of 100 nm-700 nm. Compared with the unreinforced AZ91 alloy, the grain size and morphology of Mg17Al12 phase in as-cast composites are much refined. The ageing process of composites is accelerated and the peak-aged time of composites decreases from 42 h to 22 h significantly with the introduction of TiB2 particles. Large numbers of fine Mg17Al12 in composites preferentially precipitate at grain boundaries and near TiB2 particles regions. In addition, the hardness, yield strength, ultimate tensile strength and elongation of as-cast composites are improved by 16.1%, 53.0%, 26.3% and 25.6%, respectively. After T6 heat treatment, the strength of composites is increased further due to large amounts of submicron Mg17Al12 phase, and the age hardening efficiency of composites is higher than that of AZ91 alloy.

Abstract :

To enhance the wear resistance of magnesium alloy to expand its applications, AZ91 matrix composite reinforced with TiB2 particles was developed by in-situ casting, and its tribological behavior was investigated. The dry sliding wear experiment was carried out with the sliding speeds of 0.25, 0.50 and 0.75 m/s, at different normal loads of 12.5, 25 and 37.5 N respectively. The hardened AISI 52100 bearing steel was selected as counterbody material. The experimental results reveal that the mechanical properties of composite are improved significantly due to grain refinement and numerous dislocations formed near TiB2 particles. The wear rate of composite reduces with the increase of sliding speeds at all normal loads and wear mechanism is transited from abrasive and mild oxidation wear to delamination and severe oxidation wear, similar to the wear mechanism in various normal loads. However, the mechanically mixed layer formed at higher speeds has a protective effect and the delamination and plastic deformation of subsurface is more severe at higher loads. The wear resistance of composite is greater than that of the matrix at all wear conditions, because TiB2/AZ91 composite possess improved hardness and strength, as well as increased work hardening capacity of subsurface due to the presence of nanosized TiB2 particles.

Abstract :

A theoretical study is conducted by first-principles theory to study the structural, electronic, elastic and thermal properties of Al4SiC4, Al4C3 and 4H-SiC phases under pressure. The calculated results indicated that the volumetric shrinkage of Al4SiC4 declines to 16% compared with 4H-SiC for 12% and its length of lattice parameter along c-axis decreases faster than that of along other axes in cell structures. The mechanical properties of Al4SiC4 like elastic constants and elastic moduli increase continuously under pressure. The thermal expansion coefficient of three compounds under pressure are studied first. When temperature is lower than 500 K, the coefficient increases rapidly first then gradually tends to a linear accession at higher temperature and the propensity of increment becomes moderate. The C-V data decreases slightly with pressure but increases dramatically with temperature for all compounds.

Abstract :

In this paper, dry sliding tribological properties of self-mated couples of B4C-hBN ceramic composites containing different amounts of hBN have been evaluated using a pin-on-disc friction and wear machine, and the worn surfaces of B4C-hBN specimens have been observed and analyzed by scanning electron microscope (SEM). It is found that the dry sliding tribological properties of self-mated couples of B4C-hBN ceramic composites take on obvious regularity: with hBN content increasing, the friction coefficient gradually decreases, but the wear coefficient gradually increases. The decrease of friction coefficient could be largely attributed to the formation of a transfer film formed on the wearing surface of the B4C-hBN specimens. The formation of the film is investigated.

Abstract :

Cu-Ni-graphite composites are intended for using as switch slide baseplates materials in high-speed railways industrials. The tribological characteristics of Cu-Ni-graphite composites with different graphite content were affected by physical properties and were generated variation correspondingly. It is difficult to study the correlation degree between tribological characteristics and physical properties by the means of experiments. However, grey correlation analysis (GCA) is a suitable mathematic method for researching the correlation with each factor. In this study, Cu-Ni-graphite composites were prepared by powder metallurgy and the correlation degree between tribological characteristics (Cu-Ni-graphite composites slid against U75V steel) and physical properties were calculated by GCA method. The results showed that through the calculating by GCA method, compared with physical properties of Cu-Ni-graphite composites, the most effective way to reduce the friction coefficient is to improve the relative density as well as the increasing of hardness can also bring down the friction coefficient usefully. The best way to reduce wear rate is the increasing of work of rupture and flexural strength, when these two properties have a small amount of ascension, the wear rate would be rapidly decreasing. The GCA results could help to improve materials' performance and give reasonable advices to the following studies. (C) 2017 The Authors. Published by Elsevier B.V.

Abstract :

Used as pin or disc specimens, the tribological behaviors of hot-pressed B4C-hBN ceramic composites containing different contents of hBN (0, 5, 10, 20 and 30 wt%) coupled with B4C ceramic under dry sliding condition have been investigated using a pin-disc tribometer. Experimental results show that, the dry sliding tribological behaviors of B4C-hBN ceramic composites against B4C are obviously different when B4C-hBN ceramic composites are used as pin or disc specimens, respectively. When B4C-hBN ceramic composites are used as pin specimens, with hBN content increasing, the friction coefficients of B4C-hBN/B4C pairs gradually increase; however, when B4C-hBN ceramic composites are used as disc specimens, with hBN content increasing, the friction coefficients of B4C/B4C-hBN pairs gradually decrease. The reasons that cause the discrepancy are discussed.

Abstract :

The corrosion behavior of Ni-P coating deposited on 3003 aluminum alloy in flue gas condensate was investigated by electrochemical approaches. The results indicated that nitrite acted as a corrosion inhibitor. The inhibiting effect of nitrite was reduced in solutions containing sulfate or nitrate. Chloride and sulfate accelerated the corrosion of Ni-P coatings greatly. This can provide important information for the researchers to develop special Ni-P coatings with high corrosion resistance in the flue gas condensate.

Abstract :

Effect of Mo addition on the microstructure and mechanical properties of Cr3C2-20 wt. % Ni cermet was investigated. Three different phases can be seen in the microstructure after adding appropriate molybdenum. The completely undissolved (Cr, Mo)(3)C-2 phase maintains the original grain size and effectively prevents the (Cr, Mo)(7)C-3 grains from merging and growing. The relative densities of the sintered specimens decrease slightly, while the hardness and bending strength increase firstly and then decrease slightly with the increase of Mo content. The maximum values of the hardness (88.6 HRA) and bending strength (1200 MPa) are achieved with 1 wt. % Mo addition.
