In order to study the effect of microstructural change on the tensile properties of discontinuous precipitated Al-Zn binary alloy, four different Al-Zn alloys(25, 30, 35, 45 wt% Zn) were aged at 160 °C for different aging times(0, 5, 15, 30, 60, 120, 360 min) after being solution treated at 400 °C, and successively drawn at room and cryogenic temperatures(-197 °C). Discontinuous precipitation was formed during aging in the Al matrix(which contained more than 30 wt% Zn) in Al alloys containing more than 30 wt% Zn. The tensile strength of continuous precipitated Al-35Zn alloy decreased with increasing drawing ratio, however, the tensile strength of discontinuous precipitated Al-35Zn alloy increased with further drawing. The strength and ductility combination, 350 MPa-36% was achieved by drawning discontinuous precipitated Al-Zn alloy at room temperature. The discontinuous precipitated Al-Zn alloy drawn at cryogenic temperature showed a higher value of tensile strength, over 500 MPa, although ductility decreased. †(Received July 22, 2016; Accepted August 16, 2016)
