Solid State Physics


The method of low-angle x-ray scattering is used to perform a detailed analysis of the early stage of decomposition of Al-Zn alloys with 4.41 and 9.41 at. % Zn quenched at different homogenization temperatures. The parameters that characterize the post-quench state of the alloys are determined. It is found that a reduction in the quenching temperature is accompanied by a reduction in the size of the Guinier-Preston (GP) zones and their content of the dissolved element. Here, the density of the zones also decreases. An attempt is made to establish a connection between the parameters of the GP zones and the regions containing closely-spaced lamina formed in the alloys at the homogenization temperature.
