摘要
应用光学显微镜、透射电子显微镜和机械性能试验方法，研究了１０Ｃｒ５ＭｏｗＶＴｉＢ热强钢的组织稳定性，并对电解沉淀相进行了Ｘ射线衍射相分析和化学定量分析。
The microstructure stability of 10Cr5WvTiB heat-resistingsteel is studied by meansof opitical microscope，TEM and mechanical properties，which are air-quenched and tem－perad at high temperature before teating．Long time aging is performed at 650℃. Thepercipitates extractcd from electrolytes are identified by X-ray diffraction and quantitativechemical analysis．The results show that the microstructure and mechanical properties of thesteel is stable at 650℃.
