摘要
研究了热处理对Ｃｒ１７Ｎｉ２钢组织和硬度的影响。结果表明，随淬火温度由９５０℃升高到１１００℃，组织中δ铁素体略有增加，而硬度持续增加，回火对δ铁素体数量没有影响，研究还发现该钢的硬度是基体和δ铁素体的综合贡献，存在如下近似关系式ＨＶ＝ＨＶＭ（１－ｆＦ）＋ＨＶＦｆＦ。
The effect of heat treatment on the microstructure and hardness of Cr17Ni2 steel has been studied.The results show that the amount of δ ferrite is slightly increased while hardness of the steel is continuously increased with increasing the quenching temperature from 950℃ to 1100℃,and the tempering process has no influence on the content and distribution of δ ferrite.The results also denote that the hardness of the steel is the general contribution of matrix and δ ferrite,and there is a nearly equation HV=HV M(1-f F)+HV Ff F.
