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 LY12 with without aluminum thin film was produced under low temperature of 380 oC. The microstructure mechanical properties were investigated. addition Al interlayer had largely improved interfacial shear strength joints. average LY12/Al/TC4 64.3 MPa which 2.5 times larger than joints’ strength. fracture mainly occurred on interface from XRD result surfaces.
