Abstract

See full text

Provided are an aluminum alloy clad plate for structural members, and an aluminum alloy clad structural member which have both of a high strength and formability (ductility) and further such a BH response that the plate and the member can gain a required high strength even through a high-temperature and short-period artificial aging. The clad plate is an aluminum alloy clad plate having laminated aluminum alloy layers as illustrated in FIGS. 4 and 5. The clad plate also has mutual diffusion regions in which Mg and Zn are mutually diffused between the laminated aluminum alloy layers as a phase after subjected to diffusion heat treatment, and has an inertial radius Rg and a scattering intensity I0 as shown in FIGS. 1 and 2. The factors Rg and I0 are measured by a small angle X-ray scattering technique.
