俄罗斯学者介绍了工程结构合金Mo-47wt%Re单晶体区域熔炼结晶时亚结构形成的研究结果，先前的研究多注重单晶体树枝状晶胞形貌及其纵横向纤维结构不均匀性，而本实验中对熔区移动速度(V)，结晶前沿形状对单晶内更粗大的嵌镶块大小和取向差的影响进行研究。研究中采用电子束区域
Russian scholars introduced the research results of sub-structure formation during the melting crystallization of engineering structural alloy Mo-47wt% Re single crystal. Previous studies focused on single-crystal dendritic cell morphology and its longitudinal and transverse fiber structure inhomogeneity. In this experiment The effects of the velocity of molten zone (V), the shape of the front edge of the crystal on the coarser insert size and orientation difference in the single crystal were studied. E-beam areas were used in the study
