| Abstract Scope |
Refractory metals and alloys possess unique combinations of thermophysical properties, such as high melting temperatures, high strength, excellent corrosion resistance, and high electrical/thermal conductivity, that often exceed the performance capabilities of conventional alloys. Despite the opportunities for advancing components in extreme (and often combined) environment applications, refractory metals have historically been underutilized relative to cheaper and lower performance alloys. Additive manufacturing (AM) has led to a renewed interest in the development of refractory metals by overcoming challenges associated with conventional ingot metallurgy practices. In this study, recent efforts in laser-based AM of refractory metals and alloys are presented, with a focus on laser powder bed fusion of elemental Ta and the Nb-C103 alloy. Process-structure-property relationships are characterized, emphasizing mechanical and corrosion performance. Implications of utilizing AM to accelerate adoption of refractory metal components are discussed.
