Abstract

The study results of the structure and mechanical properties of magnesium alloys obtained by rotary forging, similar in composition to the IMB7-1 alloy of the Mg-Y-Gd-Zr system, are presented. Mechanical properties were determined after rotary forging and after rotary forging with subsequent aging at 200 °C for up to 64 hours. The alloys were aged both immediately after rotary forging and after homogenization at 515 °C of the deformed alloys obtained. It is established that rotary forging contributes to the hardening of the studied alloys as a result of grain grinding and intensive twinning. Aging carried out after rotary forging leads to additional hardening of alloys as a result of the decomposition of supersaturated magnesium solid solution. Annealing after rotary forging increases the grain size in the studied alloys due to collective recrystallization and thereby reduces the strength properties of the alloys.
