Strengthening in Al-, Mo- or Ti-doped CoCrFeNi high entropy alloys: A parallel comparison

In the current work, a parallel comparison of the influence of Al, Mo and Ti, on the microstructure and strengthening of the CoCrFeNi alloy was conducted. To achieve this, inconsistencies on variables including the extent of alloying, thermomechanical processing and property-evaluation method were avoided. Microstructurally, following cold-rolling, annealing of the 4 at.% Al-doped alloys at 800–1000 °C did not result in phase separation;...
