摘要
采用光学显微镜、电子显微镜、电子能谱仪和力学性能测试方法 ,对 3Cr2 3Ni8N气门钢性能不合格原因进行了分析。结果表明 ,原材料中网状碳化物严重聚集并沿晶析出及基体组织中夹杂物分布不均匀 ,是造成气门钢性能不合格的主要原因。
Unqualified 3Cr23Ni8N valve steel was studied by optical and electron microscopy, EDS, mechanical test. It was concluded that main causes of valve steel with unqualified performance were network like precipitation of carbide along grain boundary and uneven distribution of inclusions.
