摘要
Nb/304L stainless steel composite plate was fabricated by explosive welding. Microstructure and content distribution along the interfaces of composite were studied by optical microscope(OM),scanning electron microscope(SEM) and energy spectrum(EDS). The results show that the waveform bonding can be obtained when proper dynamic parameters of explosive cladding are subjected. The interfaces undergo severe plastic deformation,which leads to the increase of hardness. There exist molten regions on both sides of wave peak and molten layers in bonding interfaces. And there is no obvious element diffusion on the both sides of bonding interface.

The results show that the waveform bonding can be obtained when proper dynamic parameters of explosive cladding are subjected. The interfaces undergo severe plastic deformation, which leads to the increase of hardness. There exist molten regions on both sides of wave peak and molten layers in bonding interfaces.
