| 中文摘要 | A bulk nanostructured Al-Zn-Mg-Cu alloy with high contents of alloy elements was fabricated by cryomilling followed by spark plasma sintering (SPS) techniques. Higher strain and lower strength were obtained in the SPS-processed Al-Zn-Mg-Cu alloy samples. This is due to the agglomeration of MgZn(2) precipitated on the contact zones of powders during the SPS process. The strength of the Al-Zn-Mg-Cu alloy can be improved further by an optimize heat treatment technique, after which the precipitation-hardening effect of MgZn(2), particles precipitated homogeneously in grain interiors was enhanced. The experimental results have shown that modifying the MgZn(2), size and distribution is beneficial to improve the mechanical property of the nanostructured Al-Zn-Mg-Cu alloy.
