Trans. Nonferrous Met. Soc. China 22(2012) 2421-2430 FEM simulation and experimental verification of temperature field and phase transformation in deep cryogenic treatment LI Jun-wan1, TANG Lei-lei1... concentrated on the specimen surface region about 1/3 of the sample thickness. Subjected to DCT, the retained austenite of quenched specimen continues to transform to martensite and finally its phase......
DSC Investigation of Phase Transitions in System LaH2-LaH3 王龙妹1 (1.Central Iron & Steel Research Institute, Beijing 100081, China) Abstract:Differential scanning calorimetry (DSC) measurements... complicated DSC signals (double, triple etc. peaks) were observed which some of them were up to 4 phase transformations. Based on these measurements and carried out on high purity samples and supported......

endothermic peaks. One is at 554 °C which is close to the temperature of formation of Mg5Gd phase according to the equilibrium phase diagram of the Mg-Gd alloy. The other is at 644 °C which is close to the melting temperature of α-Mg according to the equilibrium phase diagram of the Mg-Gd alloy. This is coincided with the result in Refs. [17-19]. Therefore, the solution treatment temperatures......
Effect of element Gd on phase constituent and mechanical property of Mg-5Sn-1Ca alloy SHI Bin-qing(施斌卿)1, 2, CHEN Rong-shi(陈荣石)1, KE Wei(柯伟)1 1. State Key Laboratory for Corrosion and Protection...: The Mg-5Sn-1Ca-xGd (x=0, 1) alloys were chosen to investigate the change in solidification paths, phase formation and mechanical properties. The microstructure of as-cast Mg-5Sn-1Ca alloy is composed......
