Abstract

TaW refractory alloys with excellent high-temperature mechanical behaviors up to 2000 ℃ have been intensively researched recently. Such performances herald great potential in industrial applications. In this study, we manufactured a Ta10W refractory alloy using selective electron beam melting with elemental TaW powder. The as-received microstructure shows high chemical homogeneity, and the obtained hardness values are 295±3 HV and 293±3 HV for XOY and XOZ planes, respectively. The yield strength of the compression tests can reach 664±8 MPa. The yield strength, ultimate tensile strength, and strain after fracturing of samples normal to the build direction of the as-deposited Ta10W refractory alloy are 750±5 MPa, 764±4 MPa, and 6.05±2.34, respectively. This study comprehensively investigated the microstructure and mechanical behaviors of the additively manufactured Ta10W refractory alloy, which can provide considerable insight into additive manufacturing of high-melting point refractory alloys.
