Dynamic StrainAging (DSA) is a strengthening phenomenon in metals and alloys caused by the interaction between the diffusive solute atoms and the moving dislocation.
动态应变时效是在金属和合金中，移动着的溶质原子和运动中的位错发生交互作用时所出现的一种强化现象。

Then the strainaging behavior of X80 grade LSAW pipe body was conducted a test simulation and the result coincide with the former analysis.
对X80钢级直缝埋弧焊管管体的应变时效行为进行了试验模拟，结果与分析相吻合。

With the strainaging temperature increasing, strength and hardness increases, plasticity and toughness decreases, yield ratio has the ascending trend, hardening index decreases.
