Summary:[Display omitted] •Development of high-entropy alloys by powder metallurgy route, using “commodity” powders.•It can be replaced fully prealloyed powders (not available in the market) by commodity powders mixing.•High entropy alloys can be easily developed, being obtained full FCC phase.•The amounts of mixing can be predicted by different proposed parameters. One of the main drawbacks of the powder metallurgy route for High-Entropy Alloys (HEAs) is the unavailability of fully pre-alloyed powders in the market. Using commodity powders (commercial Ni, Fe and Co base fully pre-alloyed powders, fully available in large quantities and at competitive prices) to produce HEAs presents a completely new and competitive scenario for obtaining viable alloys for high-performance applications.
