The bonding mechanism of explosive welding is studied. On the basis of explosive welding experiments of brass and A3 steel

the bonding boundary microstructure is made by means of microscopic examination

electron microscope scanning and transmission. The bonding zone texture is also explored. It is concluded that the two materials melt and compound during high pressure

high temperature

intense plastic deformation and diffusion which are caused by highspeed collision. Therefore

the resulted bonding zone texture is different from the original metals. The explosive welding of metal includes the characteristic of melting welding

pressure welding and diffusion welding. it is a complex process.
