Regulate the microstructure, tensile properties and fatigue crack growth behavior of an Al–Zn–Mg–Cu alloys fabricated by laser powder bed fusion via post-heat treatment

An Al–Zn–Mg–Cu–Si–Zr–Er alloy was fabricated by laser powder bed fusion technology. A unique cellular structure consisting of α-Al, Mg2Si, and Al2CuMg phases was observed in both as-printed (AP) and direct aging (DA) alloys. Direct aging treatment at 150 °C × 4 h can improve the yield strength and h...
