The pit then grows through the compressive layer, and the change in residual stress state and the pit geometry initiate stress corrosion cracking.

随后斑点穿过压缩层继续扩展，剩余应力发生改变，斑点最终导致应力腐蚀裂纹。

Almost any lack of homogeneity of the metal surface or its environment may initiate attack, by causing a difference in potential. The result is corrosion that is usually localized.

只要金属表面或它的环境缺少同一性，就可能引起电位不同、产生腐蚀，这种腐蚀常是局部性的。
