Mo70B20Si10合金在铸态1600℃退火后，在有序的Mo5SiB2 （T2）金属间相（D8l）内形成了Mo固溶体（Moss）的板状析出物。通过透射电子显微镜-选择区域电子衍射研究确定了T2基体内Moss片状沉淀的晶体取向，主要显示了{111}Mo (001)T2与Moss T2的关系。高分辨率透射电镜分析表明，经过1600℃2 150 h的长时间退火处理后，仍保持片状形貌，Moss-T2长界面保持半相干。
Upon annealing a Mo70B20Si10 alloy in the as-cast condition at 1600oC, plate shaped precipitates of a Mo solid solution (Moss) have been observed to develop within an ordered Mo5SiB2 (T2) intermetallic phase (D8l). The crystallographic orientation of Moss plate-like precipitates within the T2 matrix has been determined by transmission electron microscopy-selected area electron diffraction studies to show mainly the relations {111} Mo (001)T2 and Moss T2. Upon a prolonged annealing treatment at 1600oC for2 150 h, the plate-like morphology was still maintained and the Moss-T2 long interface remained semicoherent as confirmed by high-resolution transmission electron microscopy analysis.
