摘要

•A novel precipitation strengthened FeCoNi MEA were synthesized through powder metallurgy method.•This Al6Ti7 MEA exhibits a high yield strength (796 MPa) with moderate ductility retention (20.3%).•The high strength is mainly attributed to the highly dispersed L12 nanoparticles, leading to precipitation strengthening.
