Abstract

A range of aluminum-magnesium alloys (2 to 6 percent magnesium) have been deformed in uniaxial tension over the temperature range 300 to 500°C (572 to 932°F) and substantial increases in ductility have been demonstrated. Grain growth, however, limits ductility in the 2 percent magnesium alloy, while cavitation limits it in 6 percent magnesium alloy. It is suggested that dynamic recovery and perhaps a contribution from dynamic recrystallization are the metallurgical mechanisms responsible for this behavior.
