摘要
1.Introduction The multi-component high entropy alloys(HEAs)or medium entropy alloys(MEAs)attract reseachers’extensive attention,in particular,the single-face center cubic(fcc)HEAs or MEAs due to their some advantages,such as excellent ductility[1,2],good corrosion resistance[3]and high radiation tolerance[4].However,their strength is commonly insufficient for engineering applica-tions.Recently,many investigations are ongoing to improve their strength by traditional strengthening mechanisms,like fine-grained strengthening[5,6],solid strengthening[6-8],strain strengthening[9],polyphase strengthening[10-12],and precipitation strength-ening[13-15].Among these strengthening mechanisms,the co-herent L1_(2)-type nanoparticles precipitation strengthening has been proven to be a very effective way to improve their strength[13-15].
