近年来,氮作为钢的合金化成分之一已日益受到重视,特别是对于不锈钢的加氮问题,已有大量研究。氮在不锈钢的奥氏体相中比碳容易固溶,并有延缓碳化物析出的效果,能有效改善钢的强度和耐蚀性。同时氮是大气中取之不尽的廉价资源,如能取代钢中昂贵的镍,其经济效益可想而知。特别是 In recent years, nitrogen has been paid more and more attention as one of the alloying components of steel. In particular, there has been a great deal of research on the problem of adding nitrogen to stainless steel. Nitrogen in stainless steel austenite phase easier than the carbon solution, and delay the effect of carbide precipitation, can effectively improve the strength and corrosion resistance of steel. At the same time, nitrogen is an inexhaustible and cheap source of energy in the atmosphere. If it can replace expensive nickel in steel, its economic benefits can be imagined. especially
