TA1/X65　bimetallic　plate　has　a　bright　future　of　application　by　combining　the　excellent　corrosion　resistance　of　TA1　and　the　high　strength　of　inexpensive　X65　steel,　while　manufacturing　large　size　TA1/X65　bimetallic　plate　is　still　a　challenging　task.　Multi-pass　hot-rolling　is　the　most　common　way　to　achieve　a　large　size　bimetallic　plate.　In　this　work,　interface　characteristic　of　explosive-welded　and　multi-pass　hot-rolled　TA1/X65　bimetallic　plate　is　experimentally　studied.　The　microstructure,　composition　and　microhardness　distribution　across　the　TA1/X65　interface　are　investigated　by　optical　metallographic　observation,　scanning　electron　microscope　(SEM)　observation,　energy　dispersive　spectrometer　(EDS)　analysis,　and　Vickers　hardness　test.　Shear　tests　and　stratified　tensile　tests　are　conducted　with　emphasis　on　impacts　of　the　angle　between　loading　direction　and　detonation　wave　propagation　direction　on　interface　strength.　A　straight　TA1/X65　interface　with　periodic　morphology　of　residual　peninsula　could　be　observed　on　the　cross　section　parallel　to　detonation　wave　propagation　direction,　while　in　most　cases　there　is　no　residual　peninsula　morphology　on　the　straight　TA1/X65　interface　when　the　cross　section　is　perpendicular　to　detonation　wave　propagation　direction.　TA1/X65　interface　of　explosive-welded　and　multi-pass　hot-rolled　bimetallic　plate　presents　higher　bearing　capacity　for　the　load　perpendicular　to　detonation　wave　propagation　direction　than　that　for　the　load　parallel　to　detonation　wave　propagation　direction.　The　results　of　this　paper　have　a　certain　guiding　significance　for　the　fabrication　of　pipes　and　containers　made　of　explosive-welded　and　hot-rolled　TA1/X65　bimetallic　plate.
