| Abstract Scope |
The possibility of obtaining High Entropy Alloys (HEAs) from pre-alloyed commodity alloys/scraps easily found in the market offers a cheaper, viable, and flexible alternative to introducing these alloys in many industrial applications. In this work, the possibility of this idea is demonstrated using three different powder metallurgy (PM) methods: spark plasma sintering (SPS), laser powder bed fusion/metals (PBF-LB/M), and metal injection moulding (MIM). The three technologies are feasible to develop HEAs and can provide outstanding mechanical properties compared to alternative processing routes like casting. Moreover, these three PM technologies allow the use of commodity powders with a typical size distribution of a gas-atomized batch avoiding the direct use of critical raw materials. |
