摘要：
This paper describes the research progress in hot deformation behaviors of discontinuously reinforced aluminum (DRA) composite, including research method, deformation mechanism and hot workability. The reliability of constitutive equation and processing map for description of flowing behaviors and deformation mechanisms in the previous studies were discussed. Based on that, the strain rate and temperature sensitivities of flow stress were introduced to further identify the deformation mechanisms. Deformation characteristics and microstructures of the composites with different reinforcements were illustrated. Finally, the future researches of hot deformation of DRA composite are suggested.
