The results show that suitable cold pre-deformation can improve the alloy's plasticity and toughness obviously.

结果表明，适当的预冷变形量对改善合金塑韧性有较明显的作用。

Cold deformation results in increasing of dislocation density and inhomogeneous dislocation distribution, the latter is the direct reason for pre-strain to promote microstructural evolution.

冷变形提高了钢中位错密度，也加剧了位错分布的不均匀性，后者是预应变加速组织演变的直接原因。
