主 题:cryogenic rolling copper alloy texture evolution recrystallization behavior
摘 要:The texture evolution and mechanical properties of Cu-Ag alloys subjected to severe plastic deformation at cryogenic temperature(CT) were investigated and the sequent annealing behaviors were also *** with the sheets rolled at room temperature(RT) showing copper texture,the CT-rolled sheets exhibited brass texture which indicated that cross-slip was suppressed at CT,and both the ultimate tensile strength and yield strength of the sheets were *** to the in-situ recrystallization mechanism,recrystallization textures in as-annealed CT-rolled sheets were randomly distributed,while the as-annealed RT-rolled sheets mainly contained cube *** of the rolled and annealed sheets were observed using optical microscopy and electronic back-scatter *** results show that the dynamic recovery was suppressed during CT-rolling and resulted in higher deformation energy ***,the recrystallization of CT-rolled sheets could start at a lower temperature than that of RT-rolled sheet at the same reduction.
