Abstract

The features of quenching on the line of continuous heat treatment (CHT) of wide (2400 mm wide) cladding sheets made of high-strength aluminum alloy B95p.ch. are given. The investigations of the structure, corrosion resistance and mechanical properties in tension at different temperatures shown that the technology of heat treatment, including hardening on the CHT line and subsequent artificial two-stage aging according to the T2 modes of sheets, made it possible to provide a uniform characteristic structure, the surface quality and level of mechanical properties necessary for sheathing sheets along the width of the sheet and in different directions of rolling that meets the requirements of the aviation industry standard.
