英文摘要The WE43 sheets are prepared by single-passed rolling at 370 & DEG;C and 450 & DEG;C with total reduction of 40% and 50%, and the microstructure and mechanical properties of the sheets are contrastively investigated. The R370-40% and R450-50% alloys both exhibit non-recrystallized structures with high-density dislocations and strong basal texture. Many {1011} compression twins and {1011}-{1012} double twins are formed when rolled at 370 & DEG;C, while {1012} tensile twins are formed when rolled at 450 & DEG;C. The R370-40% alloy failures at a considerably low stain, while the ductility of R450-50% alloy is much higher than that of R370-40%. The orientation of compression twins and double twins is more favorable for the basal < a > slip, then a large deformation occurs inside twins and deformation incompatibility appears at the twin-matrix boundary in the subsequent plastic deformation, leading to the final failure. The low plasticity of R370-40% alloy is mainly caused by the activity of compression twins and double twins.
