Abstract

Homogenization annealing of wrought aluminum alloys ingots is crucial for further processes such as hot and cold deformation due to the increasing uniformity of structure and technological plasticity. The paper presents the effects of homogenization parameters under various modes on microstructure evolution and technological plasticity of 1163 alloy (Al–Cu–Mg) ingots in the temperature range of 350–470 °C. The microstructure evolution in 1163 alloy was studied by optical microscopy, transmission electron microscopy and energy-dispersive X-ray spectroscopy.
