Influence of the Mn Content on the Corrosion Behaviour of HEA CoCrFeNiMnX (X=5, 20, 35 at.%) Prepared via MA+SPS

Influence of the Mn Content on the Corrosion Behaviour of HEA CoCrFeNiMnX (X=5, 20, 35 at.%) Prepared via MA+SPS

The high entropy alloys with intended chemical compositions of CoCrFeNiMnX (X=5, 20 and 35 at.%) were prepared by the means of mechanical alloying. Prepared powders were then compacted using the progressive spark plasma sintering, which minimizes the deleterious microstructural coarsening. The compa...
