Abstract

En 中文

• Ti content governs the alloyed powders size by balancing cold-welding and fracture. • Ti addition promotes ordered phases, but excess Ti forms brittle compounds. • Al0.25CrFeNiTi0.25 achieves a strength-ductility synergy at room-temperature. • Al0.25CrFeNiTi0.35 exhibits a yield strength of approximately 997 MPa at 650 °C.
