摘要：

The hot workability of SiCp/2024 Al composite was explored by conducting hot compression simulation experiments on Gleeble-3500 under temperatures of 300-500 degrees C and strain rates of 10(-3)-1s(-1). Constitutive equation was developed through hyperbolic sine function, and the activation energy was calculated to be 151kJmol(-1). The hot processing maps referring to dynamic material model were drawn in a true strain range from -0.2 to -0.8. At the strain of -0.8, the recommended regions in processing map contained two domains: superplastic domain (500 degrees C, 10(-3)s(-1)) with an efficiency of about 0.72 and DRX domain (500 degrees C, 1s(-1)) with an efficiency of about 0.45. Together with macrostructure and microstructure observations, it was suggested to remove the DRX region.
