THERMAL STABILITY OF NON-EQUILIBRIUS MICROSTRUCTURE IN MICROALLOYED STEEL DURING REHEATING S.W. Yang1,D. Tang2,H.B. Wu2,H.T. Jiang2,X.L. He1 (1.Dept. of Materials Physics, University of Science.... The sample relaxed for 60s displayed the highest thermo-stability, whereas microstructure evolution was the quickest in the sample relaxed for 1000s even though it was the softest prior to reheating......
Thermal stability and mechanical properties of Gd-Co-Al bulk glass alloys CHEN Ding(陈 鼎)1, 2, A. Takeuchi2, A. Inoue2 1. Institute for Metal Research, Hunan University, Changsha 410082, China; 2... systems, were obtained mainly by WANG et al[9]. Among these new heavy RE-based BMGs, the Gd-based BMG is worthy to note for its high thermal stability and unique properties (e.g. magnetic and magneto......
