- Abstract
The effect of shot peening on mechanical properties and ballistic resistance of plates from magnesium alloy AZ31B 25 × 300 × 300 mm in size to the piercing action of a projectile (diameter 7.62 mm, velocity 690 m/sec) is studied. The yield strength, the ultimate strength, the elongation, the impact toughness and the microhardness of the alloy are determined prior to and after shot peening with glass beads. The surface of the internal channel of penetration of the projectile is investigated by scanning electron microscopy. The shot peening is shown to have a positive effect on the ballistic resistance of targets from alloy AZ31B.
