    摘要:

    近年来,随着难熔金属的研究与深入,传统工艺难以满足在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弹性和可加工性。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。因为选区激光熔化难熔金属对低熔点元素、加工参数等敏感,故总结了这些因素对工艺控制和最终零件质量的影响。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。

    Abstract:

    In recent years, with the development of refractory metal research, the traditional process can not meet the demand of refractory metal and its complex structure. In view of the high melting point and excellent high temperature mechanical properties of refractory metal materials, combining them with laser additive manufacturing technology will provide greater elasticity and machinability in refractory metal design. In this paper, we summarize the laser additive manufacturing technology of refractory metal materials. According to material classification, tungsten alloy, porous tantalum, molybdenum alloy and refractory high entropy alloy are reviewed. Because refractory metals manufactured by laser additive are sensitive to low melting point elements and processing parameters, we conclude the influences of these factors on process control and final part quality. Finally, including the advantages and disadvantages of the current research are, and the future development trend is prospected.
