This paper presents results concerning a systematic study of the effects of the homogenization treatment on the microstructure and on the hot workability of alloy AA 2014. For this purpose, material taken from DC ingots was homogenized in several different conditions so that the effects of homogenization variables on the microstructures' changes could be assessed. The temperature used was of 500 C and the variables studied were: homogenization time (8, 24 and 48h) and cooling rate from 500 C (water, air and furnace cooling). Optical microscopy and SEM/EDS characterization of the as-cast and as-homogenized samples could reveal the most important micro structural features of the alloy, and changes caused by the different heat treatments and the consequent solid state transformations regarding second phase particles could be determined. DSC and Thermo-Calc analysis was also done to support metallographic observations. Four contrasting microstructural conditions were selected for the hot workability studies: as-cast, homogenized at 500 degreesC for 24h followed by water cooling, homogenized at 500 degreesC for 24h followed by air cooling and homogenized at 500 degreesC for 48h followed by furnace cooling. Hot workability was characterized by hot tensile testing and by hot compression testing, to study the effects of homogenization conditions on the alloy's hot ductility and flow stress, respectively.
