摘要
TC4钛合金凭借其优异的性能在全球范围的各个领域内都有着较为广泛的应用。但随着海洋船舶、航空航天等技术发展,TC4合金构件的尺寸越来越大,传统的铸锻制造技术和新型增材制造技术均难以满足TC4大型构件近净尺寸、低成本和高效率的加工要求,因此将这两类制造技术各自优势结合起来的混合制造技术应运而生。同时,针对增材制造TC4钛合金组织内部缺陷和性能的各向异性等问题,提出了在线轧制与增材制造相结合的混合制造技术。本文结合国内外资料,对比了TC4钛合金混合制造技术的特点,总结了混合制造TC4合金构件组织和性能特征及影响因素,并提出了该技术存在的问题和发展方向,为TC4钛合金混合制造技术的研究和发展提供参考。
TC4 titanium alloy has a wide range of applications in various fields worldwide due to its excellent properties.However,with the development of marine ships,aerospace and other technologies,the size of TC4 alloy components is becoming increasingly larger,and traditional casting and forging manufacturing technology and new additive manufacturing technology have difficulty meeting the processing requirements of near net size,low cost and high efficiency of TC4 large components,so hybrid manufacturing technology combining the advantages of these two types of manufacturing technology came into being.At the same time,to solve the problems of microstructure defects and anisotropy of additive manufacturing TC4 titanium alloy,a hybrid manufacturing technology combining online rolling and additive manufacturing was proposed.Based on the existing domestic and foreign data,the characteristics of hybrid manufacturing technology of TC4 titanium alloy were compared,and the structure and performance characteristics of TC4 alloy components and the influencing factors were summarized.The existing problems and development direction of the technology were also put forward,providing references for the research and development of TC4 titanium alloy hybrid manufacturing technology.
