本文采用循环高温过热和无机盐玻璃净化剂去除液态Ni-32.5%Sn共晶合金中的异质晶核,获得高达397K(0.283T_E)的过冷度,发现深过冷熔体主要以辐射方式散热,从而导出一种根据冷却曲线近似计算其平均比热的方法,采用高速摄影技术研究了其再辉过程,发现即使过冷度超过0.2T_E,液态合金仍然优先...

The mechanism responsible for the formation of recrystallization texture in cold-rolled Ti bearing interstitial free (IF) steel sheets was investigated using electron back-scatter diffraction (EBSD). In addition, the origin of nuclei with specific orientations was studied. The formation of recrystal...
