Hot deformation behavior of hot extruded Al–6Mg alloy
Materials Science and Engineering: A, 2012Abstract The behavior of hot extruded Al–6Mg during hot deformation has been studied using hot compression test. The tests were performed at temperatures of 350, 450, and 550 °C and strain rates of 0.001, 0.1, and 1 s−1. Due to the effects of friction and adiabatic heating generated during compression, the attained true stress–true strain curves have
