With the emergence of high entropy alloys, the materials community has been striving to understand the formation mechanisms and potentially increased mechanical properties of these complex alloy systems. A parallel study of bottom-up powder and top-down solidification processing of select 3-d transition metal HEAs was carried out to investigate phase formation and mechanical properties. The bottom-up approach involved mechanically alloying elemental powders and subsequent densification via spark plasma sintering. The top-down method was arc melting. These methods allow for comparison between metastable and equilibrium phase development, and may offer insight into phase formation mechanics. Crystal structures and compositions resulting from the two processing approaches were studied and mechanical characterization was performed to help understand the complex behavior of HEAs and their tendency for stable phase formation.
