Abstract

In this study, the method of high-pressure sliding (HPS) was applied for grain refinement of an A2024 alloy. Samples in a rod shape were used in this HPS process. To achieve homogeneous grain refinement throughout the cross section of the rods, the samples were rotated around the longitudinal axis of the rod every after HPS processing. Microstructural observations revealed that the grain size was refined to 140 nm. Tensile tests showed that the samples exhibited superplasticity with a maximum elongation of 480% at 623 K and 1.0×10^-3 s^-1 and with a strain rate sensitivity of 0.36.
