摘要：
The effect of partial melting in the high strain rate (HSR) superplastic 2124 Al alloy and 20% vol% SiCp/2124 Al composite is investigated using differential scanning calorimetry (DSC). The tensile ductility and activation energy for superplastic flow are discussed based on the DSC test results. The DSC results were compared with those reported by other investigators.
