results of heat treatment processes.However, these results were insufficient to predict crack generation clearly because the mechanism relates not only to stress distributions in the parts but also... were simulated for considering a cause of the crack generation. Lastly a tentative plan was made for the future research. 关键词:Quench Cracking; Heat Treatment Simulation; [全文内容正在添加中] ......
reaction with calcium carbide and chloroform as reactants in a sealed autoclave. The morphologies and microstructures of carbon spheres before and after high temperature treatment (HTT) were... mechanism of hollow carbon spheres. Key words: carbon spheres; solvent-thermal method; microstructure; high temperature treatment 1 Introduction Mesocarbon microbead (MCMB) and C60 have been......
Influence of annealing treatment on properties and microstructures of alumina dispersion strengthened copper alloy SONG Ke-xing(宋克兴)1, 2, XING Jian-dong(邢建东)1, TIAN Bao-hong(田保红)2,LIU Ping(刘 平... with an interparticle spacing of 30-100nm. The produced 0.12%ADSC can maintain more than 87% hardness retention after 900℃, 1h annealing treatment; the recrystallization can be largely retarded......
Effect of thermal-cooling cycle treatment on thermal expansion behavior of particulate reinforced aluminum matrix composites CHEN Guo-qin(陈国钦), XIU Zi-yang(修子扬), YANG Wen-shu(杨文澍), JIANG Long-tao... and effect of thermal-cooling cycle treatment (TCCT) on the thermal expansion behaviors of three composites were investigated. The results show that the composites are free of porosity and SiC/Al2O3......
