摘要(Abstract):
采用OM、SEM、EDS、EPMA、显微硬度和剪切试验等方法,研究了H62黄铜中间层20钢/304不锈钢瞬间液相扩散结合区组织与性能。结果表明,结合区发生Fe、Cr、Ni、Cu、Zn原子互扩散,异种金属界面获得良好的冶金结合,抗剪强度可达到270 MPa以上;碳钢/黄铜界面有含Cr、Cu、Ni、Zn的"岛状"富铁相形成,扩散温度由950℃增加至1100℃,岛状组织形态由不连续状转变为连续状,并向黄铜中间层中生长,随着扩散时间的延长,贯穿于中间层,使结合区硬度增加,抗剪强度提高;950℃扩散复合,碳钢/黄铜界面有铬碳化物形成,剪切断裂发生该处,断口呈脆性穿晶断裂;1100℃扩散复合,碳钢/黄铜界面无铬碳化物形成,剪切断裂发生在黄铜/不锈钢界面,断口呈韧性断裂。
关键词(KeyWords): 碳钢/不锈钢;瞬间液相扩散复合;H62;抗剪强度
