馏分1、3、10、15的界面膜中易发生片状结构的滑移，其扩张粘度基本上不随扩张频率的变化而变化。
The sliding movement between piece structures is easy to take place in DQ1, 3, 10, 15, resulting their dilatational viscosity unchangeable with the dilatational frequency increasing.
疲劳损伤随加载周期依次表现为加载区的屈服、加载区外围即滑移区的虫蚀状磨损和片状剥落，以及随后出现大块脱落。
According to the loading cycles, the fatigue damage represented bend in loading area, worm - eaten abrasion or exfoliation around loading area and sequent massive exfoliation.
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.
