Fracture Behavior of AlSi10MnMg Alloy and Development of Heat Treatment Free Alloy
Based on die casting AlSi10MnMg alloy,the microstructure and fracture behavior of the externally solidi-fied crystals(ESCs-αI and ESCs-IMCI)were focused on.The results indicate that coarse ESCs play an important role in the fracture process of die casting AlSi10MnMg alloy.On this basis,ESCs-αI is refined and ESCs-IMCI is opti-mized by microalloying,and a novel heat treatment free THAS-1 die casting alloy is developed to realize trial produc-tion for shock tower components.
