Characteristics of plastic deformation of stress minerals in veins, such as subgrain tectonics, deformation, lamellae and deformation bands, can be found.

金矿的形成富集与韧性剪切带多期(次)活动密切相关，尤其是韧脆性变形期。

A new phenomenon of re-dissolution of second phases and re-formation of supersaturate solid solution found in processes of severe plastic deformation was summarized.

综述了在室温强塑性变形过程中发现的新现象:第二相颗粒的回溶,合金基体重新形成过饱和固溶体。

As the material is deformed beyond the strain that elastic deformation persists, the stress is no longer proportional to strain, and permanent, nonrecoverable, or plastic deformation occurs.

当材料的形变超出弹性形变发生的范围，其应力将不再与应变成正比，永久的、不可回复的形变发生，即为塑性形变。
