摘      要：Interfacial structure greatly affects the mechanical properties of laminated ***,the critical material properties that impact the interfacial morphology,appearance,and associated bonding mechanism of explosive welded plates are still *** this paper,the same base plate(AZ31B alloy)and different flyer metals(aluminum alloy,copper,and stainless steel)were used to investigate interfacial morphology and *** and TEM results showed that typical sine wave,wave-like,and half-wave-like interfaces were found at the bonding interfaces of Al/Mg,Cu/Mg and SS/Mg clad plates,*** different interfacial morphologies were mainly due to the differences in hardness and yield strength between the flyer and base *** results of the microstructural distribution at the bonding interface indicated metallurgical bonding,instead of the commonly believed solid-state bonding,in the explosive welded clad *** addition,the shear strength of the bonding interface of the explosive welded Al/Mg,Cu/Mg and SS/Mg clad plates can reach up to 201.2 MPa,147.8 MPa,and 128.4 MPa,*** proposed research provides the design basis for laminated composite metal plates fabrication by explosive welding technology.
