摘要
搅拌摩擦焊接技术是一种环保、低成本的固相连接技术,已经在航空航天、轨道交通和新能源汽车等领域得到广泛应用。对于高熔点合金材料如钛合金和不锈钢的搅拌摩擦焊接而言,搅拌头材料成了主要制约因素。钨铼(W-Re)合金凭借其高熔点、高硬度和强抗腐蚀性等优点,已成为研究和应用最热的搅拌摩擦焊接高熔点合金的搅拌头材料。本文综述了近年来在搅拌摩擦焊工艺中以W-Re合金作为搅拌头材料的制备方法、复合强化技术和应用场景的研究进展。此外,还展望了拓宽W-Re合金在搅拌摩擦焊领域应用的前景,包括降低W-Re合金的生产成本和提高其服役寿命等方面,旨在推动W-Re合金搅拌头材料在搅拌摩擦焊领域的进一步应用和发展。
Friction Stir Welding(FSW),as an environmentally friendly,cost-effective solid-state joining technique,has been widely ap‐plied in the fields of aerospace,rail transportation and new energy vehicles.However,when it comes to the FSW of high-melting-point alloy materials like titanium alloys and stainless steels,the choice of the tool material becomes a major limiting factor.Tungsten-rhenium(W-Re)alloy,with its high melting point,high hardness and corrosion resistance,has emerged as the most promising tool material for FSW of high-melting-point alloys.This review article summarizes the research progress in the preparation methods,composite reinforce‐ment techniques,and application scenarios of W-Re alloy tool materials for FSW in recent years.Additionally,it provides an outlook on expanding the applications of W-Re alloy in the field of FSW,including efforts to reduce production costs and enhance its service life.The aim is to promote further application and development of W-Re alloy tool materials in the field of FSW.
