Keywords:refractory high-entropy alloy (RHEA)、HfMoNbTaTi、precipitation strengthening、high temperature property、segregation

A novel precipitation strengthened RHEA HfMoNbTaTi was studied in as-cast condition with outstanding strength at high temperatures. The dense nanoscale precipitate was firstly obtained in RHEAs.
