WMoVTi RHEAs with different strengthening phases were fabricated by mechanical alloying and vacuum sintering. The effects of composition on phase stability, intermetallic phase formation, microstructural evolution, and strengthening mechanisms were investigated and correlated with hardness and compressive properties.
