Meanwhile, the tip of precipitates along grain boundary becomes obtuse, the alloying elements are depleted in the region near the grain boundary and the stress corrosion resistance is bettered.
同时，晶界沉淀物的端部由尖锐变得圆钝，晶界临近区域中的合金元素贫化，使材料的应力腐蚀抗力提高。
High nitrogen and low nickel stainless steels exhibit attractive properties as high strength and ductility, good corrosion resistance and reduced tendency to grain boundary sensitization.
高氮低镍不锈钢具有良好的强度、延展性及耐腐蚀性能，且可以降低晶界的腐蚀敏感性。
The main cause of better corrosion resistance was due to growth of granules, decrease of grain boundary area, and formation of thick and compact oxidation film on the coating surface.
晶粒长大、晶界面积减少以及镀层表面生成较厚的、致密的氧化膜是耐蚀性提高的主要原因。
