报道了WE54合金拉伸变形过程中的锯齿状流动。观察到的静态应变时效效应和负应变速率敏感性表明，锯齿状流动是由于位错和溶质原子之间的相互作用，称为动态应变时效(DSA)。分析了拉伸性能与DSA效应的关系。
Serrated flow in WE54 alloy during tensile deformation is reported. The observed static strain ageing effect and negative strain rate sensitivity suggest that the serrated flow is due to interactions between dislocations and solute atoms, known as dynamic strain ageing (DSA). The tensile properties are analysed in relation to the DSA effect.
