| 摘 要： | 采用加压感应熔炼+模铸和热轧+水冷、轧后+固溶处理两种工艺,制备氮的质量分数为1.0%的高氮钢材料,对不同处理工艺下材料的微观组织、力学性能、耐腐蚀性能进行研究。结果表明,抗拉强度、屈服强度、屈强比差别不明显,但延伸率和断面收缩率在固溶处理后得到明显提高。经透射电镜电子衍射发现奥氏体组织中存在大量的孪晶、位错和层错;晶内、晶界有碳化物沉淀相析出,位错强化和第二相沉淀析出强化是提高高氮钢强度的主要原因。

| Abstract: | The high nitrogen steel of 1.0% nitrogen content was prepared by two technological processes of pressurized induction melting,cooling after hot rolling and solution heat treatment after rolling.Microstructure,mechanical properties,and corrosion resistance of the materials were studied.The results show that the tensile strength,yield strength,and yield ratio have little difference for two kinds of processing.However,elongation and area reduction rates are improved after solution treatment.TEM analysis shows ... |
