摘要
研究了Al-Zn-Mg系合金经时效-回归-再时效多级热处理后硬度（HRA）的改变.用小角X射线散射研究了多级时效热处理中合金微结构的改变和硬度改变的机理.
In this paper the hardness change of Al-Zn-Mg alloy during aging-retrogression-reaging treatments was studied. The microstructure change and the mechanism of the change in hardness were studied by small-angle X-ray scattering.
