摘要：
Changes in the microstructure and mechanical properties of commercial aluminum alloy AMg6 after recrystallization have been studied. This alloy was recrystallized by two methods, namely, by annealing in air at temperatures of 250-450°C for 20 min in an electrical resistance furnace and by passing an electrical current pulse (with a duration of about 102 μs), which was generated by discharging a bank of capacitors. It was shown that the electrical pulsed treatment allows one to produce a fine-grained structure in the AMg6 alloy with a grain size (2-3 μm) less than after annealing in a furnace and to improve the mechanical properties of this material.
