Abstract
High temperature deformation behavior of as-cast Al-3Mg-0.25Sc alloy was characterized in a wide range of temperatures 573 K to 773 K (300 °C to 500 °C) and strain rates (0.001 to 10 s−1). A threshold stress behavior is observed in the temperature range of 573 K to 673 K (300 °C to 400 °C) due to interaction of dislocations with precipitates. In the temperature range of 573 K to 623 K (300 °C to 350 °C), the dislocations are pinned by precipitates, following Orowan-bowing mechanism. At 673 K (400 °C), the dislocations bypass the particles by climb process. At high temperature and low strain rate of 723 K (450 °C), and 0.001 s−1, respectively, the alloy exhibited high efficiency of power dissipation for optimal hot working process.
