In situ high-entropy solid solution and ceramic particles co-reinforced Ni-based composites with outstanding strength-ductility synergy and good pitting resistance

In present work, a novel Ni-based composite co-reinforced by in-situ solid solution and ceramic phase through a decomposition of metastable dual-phase (CoCrFeNiMn)90Al10 high-entropy alloy (HEA) was fabricated by spark plasma sintering (SPS). The SPS-ed composites with high relative density are comp...
