摘要：

The superplastic response of commercial 5083 alloy (Al-4.42Mg) under uniaxial tension at strain rates ranging from 5x10(-5) to 10(-2)s(-1) in the temperature interval 400 similar to 550 degrees C was systematically studied in this paper. The tensile test was conducted on samples of rolling direction. The maximum elongation-to-failure of 486% was found at the temperature of 500 degrees C and strain rate of 10(-4)s(-1). To identify the main charecteristics of superplastic deformation of the alloy, the microstructure and fracture of the alloy are analyzed as a function of strain, strain rate and temperature using optical microscopy (OM) and electron microscopy (SEM). The strain rate sensitivity (m) of the alloy was also studied.
