在屈服应力反常的温度范围内，研究了二元化学计量比NiAl单晶中流动应力的应变率依赖性。在400K以下，流动应力与应变率无关，但随着应变率的改变，流动应力暂时发生变化。这种应变率不敏感性可以用假设流动应力由移动位错的增殖和固定控制的假设来解释。
The strain-rate dependence of flow stress in single crystals of binary stoichiometric Ni Al has been studied in the temperature region of the yield3 stress anomaly. Below 400 K, the flow stress was found to be independent of strain rate, although it changed temporarily when the strain rate was changed. The strain-rate insensitivity can be explained by assuming that the flow stress is controlled by the multiplication and immobilization of mobile dislocations.
