based on the calculated temperature distributions and curves, especially, the fastest heated and slowest-heated temperature-distance profiles. A case study is carried out for the heat treatment...Modeling and Simulation of Heat Transfer in Loaded Continuous Heat Treatment Furnace () 摘要:Continuous furnaces are widely used in the heat treatment of mass-produced parts. However, the heating......

, XRD, SEM and EDS. The mechanisms of microstructure evolution were discussed. The results show that, after high temperature heat treatments, the Mg12ZnY phases still exist. During solution-treatment... relationship with the α-Mg matrix crystals. The temperature of solution heat treatment was determined on the basis of Mg-Gd and Mg-Y phase diagrams, and DSC curves[4-5, 11]. The microstructure evolutions......

, and the effect of heat treatment on microstructure of CuAlBi alloy was also discussed. The results show that the phase-transition point temperature of CuAlBi alloy is 561.7℃, and heat treatment can...Effect of Heat Treatment on Microstructure of CuAlBi Alloy Chen Fang1,Zheng Yucai1,Liu Changrong1,Xiao Nianxin1,Zhang Hailong1 (1.Department of Machinery and Electron, Hebei Normal University......
in this paper. In Re-5% alloy, with increasing of the heat treatment temperature and prolonging the holding time, the volume fraction of TCP-phase decreased and the TCP-phase size increased. At relatively lower... will change from needle-like and block-like to sphere when the temperature increases. The TCP-phases formed in these two Ni-Mo-Cr-Re alloys are σ and P phase.
