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。
Dynamic Strain Aging (DSA) is a strengthening phenomenon in metals and alloys caused by the interaction between the diffusive solute atoms and the moving dislocation.
位错移动导致的塑性变形或两个相邻原子面的剪切位移。
Plastic deformation as the result of dislocation motion; also, the shear displacement of two adjacent planes of atoms.
滑移面和该面上一个滑移方向的组合称为一个滑移系，晶体滑移（如位错的移动）可以沿该系统发生。
The combination of a crystallographic plane and, within that plane, a crystallographic direction along which slip (i. e. , dislocation motion) occurs.
