Al–Zn–Mg–Cu alloy with both high strength and high plasticity fabricated with wire arc additive manufacturing

Abstract: To overcome the strength-ductility trade-off dilemma, the microstructure of Al-Zn-Mg-Cu alloy was controlled by adding TiN nanoparticles and heat treatment successively. Al-Zn-Mg-Cu alloy deposition with both high strength and high elongation was achieved. The tensile strength, elongation, and microhardness were increased by 122.3%, 173.9%, 86.1%, and 82.5%, respectively. The columnar grains were completely transformed into equiaxed grains with the addition of TiN particles and the grain size was reduced by 92… Show more
