The results showed that plastic deformation at both -70℃ and 180℃ made the dislocation density of AISI304 stainless steel increase with the increase of deformation. Martensite phase transformation was induced for deformation at -70℃, whereas it was not at 180℃. As the dislocation density increased, the breakdown potential of AISI304 stainless steel's passive film became a little more positive. As martensite phase content increased, it became more negative and pitting corrosion resistance decreased.

结果表明：加热180℃和低温-70℃条件下塑性变形均使AISI304不锈钢中位错密度随变形量增大而增加，AISI304不锈钢在-70℃条件下塑性变形时部分奥氏体相转变为马氏体相，而在180℃条件下塑性变形时不发生马氏体相变；位错密度的增加使AISI304不锈钢钝化膜的击穿电位略微正移，而马氏体相的增加使击穿电位呈负移趋势，材料耐孔蚀性能降低。
