  High entropy alloys (HEAs) represent a novel frontier in metallurgical
advancements, offering exceptional mechanical properties owing to their unique
multicomponent nature. This study explores a novel strategy utilising commodity
powders - Ni625, Invar36, and CoCrF75 - to tailor HEAs via metal injection
moulding (MIM). The objective is to achieve cost-effective manufacturing while
maintaining desired properties. The research involves mixing these powders in a
specific proportion, integrating them with a sustainable polyethylene
glycol-cellulose acetate butyrate binder system, and characterising the
resulting feedstocks for MIM processing. Subsequent debinding and sintering
steps were executed to densify and form a single face-centered cubic (FCC)
phase HEA, followed by comprehensive analyses to evaluate the suitability of
the developed HEA compositions. In addition, all MIM stages were thoroughly
characterised to control the porosity of the final parts and to ensure a single
FCC solid solution with promising mechanical properties in the developed
non-equiatomic CoCrFeNiMox-type HEAs.
