变形程度是影响片状组织球化的主要因素。
The deformation degree is the major factor of globularization.
相变点以上得到片层组织，片状组织的断裂韧性高于等轴组织。
The fracture toughness of lamellar microstructure is higher than that of equiaxial microstructure when deformed above the phase transition.
低温下粗大的片状组织比等轴组织具有更高的拉伸延性，且合金的变形是由孪生变形和滑移变形共同作用的结果。
Tensile ductility of lamellar microstructure is higher than that of equiaxed one at 20 K. Its deformation process consists of twinning and slipping.
