Abstract Scope |
High entropy alloys (HEAs) obtained by powder metallurgy (PM) can follow many processing routes. In this work, we propose the use of commercial commodity powders like superalloys as raw materials. There are no readily available pre-alloyed powders in the market for even the commonly studied HEAs because of which there is a need for atomizing/mechanical alloying the elemental powders before proceeding with the other PM steps. Moreover, the use of pure elemental powders has issues with health, storage and handling. But the commodity powders (those compositions most extended in most applications) are fully available in the market in gas atomized form, which can be blended in the right proportion to obtain a feedstock to make HEAs efficiently using most PM forming technologies. In this work, we will present an approach to this technological option, where we use field assisted techniques and selective laser melting to successfully obtain single phase HEAs. |
