In this paper the hot deformation behavior of Al-5083 commercial alloy is studied. For this purpose, hot tensile tests have been carried out at various temperatures and strain rates. Velocity jump tests have been performed to determine stress-strain rate curves at various temperatures and strains. The microstructures have been studied by optical and electron microscopy (SEM). it is found that continuous recrystallization occurs during hot deformation of the AA5083. Maximum elongation about 250% is obtained at 450 degrees C and strain rate of 0.005 s(-1). The failure surface is narrow and failure occurs by necking. (C) 2008 Elsevier Ltd. All rights reserved.
