摘要
通过加热一冷却一组织分析法，研究了含铌基体钢６５Ｃｒ４Ｗ３Ｍｏ２ＶＮｂ（简称６５Ｎｂ）从１５００℃至室温不同温度下，钥所处的相区及不同冷速条件下相组成的变化，初步探讨了６５Ｎｂ钢中的相关系。
By means of a heating-cooling and microstructure analysis,an investigation is made on the phase regions at 1 500 ℃ to room temperature and the change of phase constituents at different cooling rates on the matrix steel type 65Cr4W3Mo2VNb(steel 65Nb for short)。Experimental results show that,during cooling from 1 500 ℃ to room temperature , steel 65 Nb goes through the following phase regions:L,L+F,L+F+A , L+A,L+A+M6C,A+M6C,A+M6C+M3C and F+M6C+M3C.
