Hot Deformation Behavior and Processing Map of 5356 Aluminum Alloy

Abstract

The hot compression deformation of 5356 aluminum alloy was performed with the deformation temperature 300∼500°Cand the strain rate 0.01∼10s−1 by using Gleeb1e-3500 thermal mechanical simulator. The microstructure of the alloy was analyzed by ZEISS metallographic microscope. The results show that the flow stress of 5356 aluminum alloy decreases with the increase of deformation temperature and increases with the increase of strain rate. 5356 aluminum alloy is mainly dynamic recovery under low strain rate conditions, such as 0.01 S−1, 0.1 S−1. The alloy is discontinuous dynamic recrystallization under high strain rate conditions, such as 1 S−1, 10 S−1. The hot processing map of 5356 aluminum alloy was established with the strain of 0.2∼0.5, can provide an effective data reference for the development of high-end 5356 aluminum alloy wire continuous rolling process.
