Effect of Post-weld Heat Treatment on the Microstructure and Corrosion Resistance of Deposited Metal of a HighChromium Nickel-Based AlloyXin-Jie Di1,Xiao-Qian Liu1,Cui-Xin Chen2,Bao-Sen Wang3,Xiao...) of a high-chromium nickel-based alloy was investigated after the post-weld heat treatment(PWHT) at 650,750,850,and 950 ℃,respectively.With the increase in temperature,the morphology of the Cr23C6......
Effect of Rare-earth Element La on Co-base Superalloy王淑荷,戴彤孚,师昌绪摘 要:<正> The effect of La element on the mechanicalproperties and constitution nearby grain boundaryin a Co-base superalloy Co-22Ni-22Cr-14k during760℃ ageing has been investigated by AES andmaterial testing. Results show that elementLa can be in a state of solid solution andsegregates......
automaton(CA) model was developed to predict the microstructure of recrystallization in single-crystal(SX) Ni-based superalloy.The quasi-static compressive tests of [001] orientated SX DD6 superalloy were conducted on Gleeble3500 tester to calibrate the CPFE model based on crystal slip kinematics.The simulated stress-strain curve agrees well with the experimental results. Quantitative deformation......
