【摘要】 采用X射线衍射仪、光学显微镜和电化学分析等方法,研究了固溶/时效处理对奥氏体耐热钢组织与性能的影响。结果表明,奥氏体耐热钢经固溶/时效处理后,其组织为奥氏体基体及弥散分布的碳化物M6C和金属间化合物Laves相,合金具有良好的耐热性,工作温度可达700~850℃。更多还原

【Abstract】 Effects of solid solution/aging on microstructure and properties of austenitic heat resistant steel were studied by X-ray diffraction meter,optical microscope and electron-chemical analysis.The results show that after solid solution/ageingt the steel′s microstructure consists of austenitic base,dispersed carbides M₆C and metallic compound Laves phase.The new alloy has superior high temperature mechanical properties and oxidation resistance.Its working temperature can be reached 700～850℃.更多还原
