摘要
2024 Al alloy has been friction-stir welded (FSW) at a starting temperature of -30 °C, and maximum weld zone temperatures did not exceed about 140 °C. The residual FSW zone grain structure consisted of equiaxed, fine-grains having a uniform size of about 0.8 μm throughout. This compares with a central weld zone grain size of about 10 μm in 2024 Al FSW at a starting temperature of 30 °C, where the weld zone temperature maximum was measured to be 330 °C.
