Abstract

Refractory high-entropy alloys are attractive for high-temperature applications, but are challenging to process. Here, a method is shown for identifying a processing window that allows the additive manufacturing of a TiZrNbTa refractory alloy with a low defect content and mechanical properties comparable to as-cast samples.
