| Abstract: | In this paper the fabrication and precipitation hardening behavior of bulk nanostructure A17075 alloy is investigated. In order to produce this alloy, the elemental powder based on the nominal composition of conventional A17075 alloy is milled up to 15 h and then hot pressed. The milled and hot pressed samples are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and differential thermal analysis (DTA). The results show that after 15 h of milling, the alloying elements are dissolved in Al matrix and a supersaturated solid solution with average crystallite size of about 30±5 nm is obtained. Hot pressing the powder samples at 500°C under 400 MPa led to the fully dense bulk nanostructure A17075 alloy. The consolidated sample has a hardness value of 165 HV which increases to 240 HV after appropriation hardening. |
