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.
