| Abstract Scope |
The potential of AM suitable refractory alloys to replace conventional high-performance materials in extreme environments has dramatically increased interest in development of novel refractory alloys to fit these applications. A challenge for novel refractory alloy development has been sourcing these powders at a reasonable cost and lead time. This presentation details how ICME was leveraged to develop three novel tungsten heavy alloys (WHAs) which were produced in small quantities (<5 kg), and further characterized to down select to one alloy. Rather than a more accessible process such as mixing of elemental powders which can be impacted by differences in powder shape, size, and density, the selected alloy was produced in a 150 kg batch size by mechanical alloying and spheroidization. Room temperature mechanical properties, characterization of LPBF builds, and how this process can be leveraged to synthesize and test novel alloys in an accelerated timeline will be discussed. |
