High-temperature mechanical response of 2196 Al‒Cu‒Li extrusions controlled by abnormal grain growth within longitudinal weld seams

This study investigated high-temperature mechanical performance of 2196 Al‒Cu‒Li extrusions with different heat treatments. At 100°C, extrusions’ performance is close to that at room temperature. At 200°C, the strength decreases by 10%, and at 300°C, it decreases by more than 30%, which is attribute...
