摘要
分析了真空自耗电弧炉(VAR)生产的TA13合金铸锭Cu元素偏析的特点及其影响因素。根据Cu偏析的规律,制定了控制Cu偏析的措施。结果表明:适宜的配料方式、混料工艺、合理的熔化工艺和补缩工艺,可以有效控制Φ700 mm TA13大规格铸锭中Cu元素的宏观偏析。
The characteristics and influencing factors of copper segregation in TA13 titanium alloy ingots produced by vacuum arc remelting( VAR) furnace were analyzed. According to the characteristics of copper segregation,measures for avoiding copper segregation were taken. The results show that suitable ingredients approach and compounding technology, reasonable melting and feeding process can effectively avoid copper segregation in large size TA13 alloy ingots with 700mm diameter.
