Abstract

The hot working behavior of commercial Al-2.5 wt pct Mg alloy 5052 was studied using hot torsion testing to simulate commercial hot rolling. The effects of homogenization time and temperature, and deformation temperature on the flow stress and hot ductility were carefully assessed. Microstructural characterizations and differential thermal analyses were performed to help explain the torsion data obtained. Significant variations in hot working behavior were noted for material machined from different regions of the commercial ingot studied. The constituent particles were found to play a significant role in determining the hot ductility of the alloy.
