摘　　要：近年来,难熔金属研究的逐步深入,传统工艺难以满足制备难熔金属及其复杂结构的需求。鉴于难熔金属材料的高熔点和优异的高温力学性能,将其与选区激光熔化技术相结合,将为难熔金属的设计提供更大的空间与可加工性。本文对难熔金属材料的选区激光熔化技术进行了总结,按照材料分类,对钨合金、多孔钽、钼合金以及难熔高熵合金进行评述。因为选区激光熔化成型难熔金属过程对合金成分和加工参数等较敏感,故总结了这些因素对工艺控制和零件质量的影响。最后,归纳了当前研究的优势和不足,并对今后的发展趋势进行了展望。In recent years,refractory metals have been progressively researched and traditional processes have difficulty in meeting the demands of preparing refractory metals with complex structures.Given the high melting points and excellent high-temperature mechanical properties of refractory metal materials,combining them with selective laser melting technology will provide greater scope and processability for the design of refractory metals.The selective laser melting technology for refractory metal materials was summarized,and tungsten alloys,porous tantalum and molybdenum alloys as well as refractory high entropy alloys were reviewed according to material classification.As the process of selective laser melting of refractory metals is sensitive to alloy composition and processing parameters,the influence of these factors on process control and part quality was summarized.Finally,the strengths and weaknesses of the current research were summarized,and future trends were outlined.
