Abstract Scope |
Understanding that successful alloy development depends on a process, a composition and economic constraints, this talk aims to guide the recent explosion of interest in refractory multi-principal element alloys (R-MPEAs) with some context on the processing of these materials. We review the paths used for manufacturing of refractory alloys with an eye toward the lessons from the last 70 years. In addition to the technical challenges associated with high melting temperatures, contamination control and thermomechanical processing we will present some of the more practical concerns that have prevented alloy adoption in the past that concern modern alloy designers. Looking forward to the exciting potential of R-MPEAs we will explore some of the challenges of emerging technologies (e.g. powder and Additive Manufacturing, computational tools) informed by past research and experience. |
