Austenitic HEA/MPEA : from the Cantor alloy to precipitation hardened Co-free alloys with optimised mechanical resistance
2023.03.27 11:01 - Katarzyna KuźniarFor nearly twenty years now, the academic – and increasingly industrial – world has been interested in new classes of metallic alloys. HEA (high entropy alloys), which are concentrated, single-phase alloys based on several metallic elements and whose Cantor alloy (Co20Cr20Fe20Mn20Ni20) is the archetype, were quickly supplemented by multiphase alloys, CCA (complex concentrated alloys) or MPEA (multi principal elements alloys) in which secondary phases bring improvements in properties.
