Spheroidizing Process of Carbide of Fe-1.5C-1.5Cr-1.5Al Steel and Its Mechanical Properties

对Fe-1.5C-1.5Cr-1.5Al超高碳钢碳化物的球化工艺及力学性能进行了研究.扫描电镜观察表明,加入铝,可抑制锻后空冷条件下先共析网状碳化物的析出;利用铝合金化作用和成分不均匀化奥氏体加热控制,提出了2种无形变球化处理工艺:①离异共析等温球化;②预冷淬火+高温回火.2种球化处理工艺均能获得良好的球化组织和良好的综合力学性能:Rm≥1 000 MPa,Re≥700 MPa,A10=10%～14%.拉伸断口具有明显的缩颈,断口形貌呈具有典型的韧窝特征.
