摘　　要：采用金相显微镜、X射线衍射仪等测试手段和电化学分析的方法,对新型双相铁基堆焊合金的热处理工艺进行了研究。结果表明:该合金具有良好的耐热性。经不同的固溶时效处理工艺,获得了(α+γ)双相基体和弥散分布的M6C、Laves相等强化相。最佳的固溶时效处理工艺为:1160℃×2h水冷+810℃×5h空冷。The heat treatment technology for two-phase iron-based high temperture alloy was studied by means of metallographic microscope, X-ray diffractometer and analysis of electron-chemistry. The results show that the aging microstmcture of the alloy consists of double basic phases （γ＋α） and disepersed carbites M6C, intermediate phase Laves. The new alloy has superior high temperature mechanical properties and oxidation resistance.The optimun solution and aging process is solution at 1160℃ for 2h,then quenched in the water,aged at 810℃ for 5 h.
