摘要：

LY12/TC4 joints have wide applications in many industrial areas such as aerospace, nuclear and chemical industries. In the present study, TC4 alloy and LY12 alloy with and without aluminum thin film was produced under low temperature of 380 degrees C. The microstructure and mechanical properties of the joints were investigated. The addition of the Al thin interlayer had largely improved the interfacial microstructure and shear strength of the joints. The average shear strength of LY12/Al/TC4 joints was 64.3 MPa which was 2.5 times larger than the LY12/TC4 joints' strength. The shear fracture mainly occurred on the interface of LY12 and TC4 from the XRD result of fracture surfaces.
