摘要
钛合金因其出色的综合性能在船舶、汽车、航空及医疗领域起着不可替代的作用,且钛合金铸件具有良好的耐腐蚀性,是舰船制造的理想材料.但钛合金在使用过程中还存在一些问题,例如成本高、冶炼难度大等,在一定程度上限制了其在船舶上的应用和发展.综述了真空自耗电弧炉熔炼、电子束冷床炉熔炼、等离子冷床炉熔炼、粉末冶金及增材制造5种制备钛合金产品技术的工艺原理、产品特点及国内外的发展状况,对各种工艺的数值模拟成果做出总结,并对未来中国钛合金体系做出展望,以期对钛合金产品制备工艺的优化提供参考.
Abstract
Titanium alloy plays an irreplaceable role in ship,automobile,aviation and medical fields due to its excel-lent comprehensive performance,and titanium alloy casting has good corrosion resistance,which is the ideal material for shipbuilding.However,the application and development of titanium alloys are somewhat constrained by challen-ges such as high costs and complex smelting processes.The process principles,product characteristics and develop-ment status at home and abroad of five kinds of titanium alloy product preparation technologies,including vacuum arc remelting,electron beam cold hearth melting,plasma arc cold hearth melting,powder metallurgy and additive manufacturing,are reviewed.The numerical simulation results of various processes are summarized,and the future titanium alloy system in China is prospected,in order to provide reference for the optimization of titanium alloy product preparation process.
