| Abstract Scope |
One obstacle to developing HEAs is the need to use many alloying elements, which are considered critical and strategic and expensive metals. However, it has been demonstrated[1,2] that HEAs can be obtained from combinations of commodity alloys (e.g., nickel and cobalt-based superalloys or stainless steels). This possibility opens up the prospects for the development of HEAs using raw materials that can come from the recycling of commodity alloys, which are available sources of metals such as Ni, Fe, Co, Cr, or Mo, which, being available in the form of scrap, lose their critical character and offer a cheaper possibility than the direct use of pure metals. In this work, non-equiatomic high entropy CoCrFeNiMox alloys are developed from three PM routes: SPS, LBPF (additive manufacturing), and MIM. [1] J.M. Torralba, S. Venkatesh Kumarán, Mater.
