Effects of deformation temperature and rate on compressive deformation behaviour of Y112 die cast aluminum alloy in semi-solid state YANG Ming-bo(杨明波), HU Hong-jun(胡红军), TANG Li-wen(唐丽文), DAI Bing.... Furthermore, when the deformation rate keeps a constant, the compression stress decreases along with the deformation temperature increasing, and when the deformation temperature keeps a constant......
and deformation of the workpiece can be predicted precisely based on ANSYS software. The simulated results show that the temperature of the divided element decreases faster at the edge than...Numerical Simulation of Temperature and Stress Fields of Ti-Alloy Thin-well Barrel during Quenching Process LI Yan-zeng1,WU Kun1,YAN Mu-fu1 (1.School of Materials Science and Engineering, Harbin......
