摘　　要：应用光学显微镜、透射电子显微镜和力学性能试验研究了１０ｃｒ５ＭｏＷＶＴｉＢ热强钢的组织稳定性。试验钢经空淬和高温回火后，在６５０℃进行长期时效试验，并对电解沉淀相进行Ｘ射线相分析和化学定量分析。试验结果表明，１０ｃｒ５ＭｏＷＶＴｉＢ钢在６５０℃下，组织结构和性能保持稳定。The microstructure stability of 10Cr5MoWVTiB heat-resisting steel has beenstudied by means of optical microscope, TEM, and mechanical testing. The steel is air-quenched and tempored at high temperature before testing. Long time aging is performed at650℃. The precipitates extracted from electrolytes are identified by X-ray diffraction andquantitative chemical analysis. The redts show that the microstructure and mechanicalproperties of the steel are stabile at 650℃.
