Investigation on Interface of Explosive Welded Pb1-Q245R Clad Plate

Interface of lead-steel clad plate was investigated by means of resistance strain gage instrumentation,OM and TEM.The results showed that the interface of the clad plate has a superior character in electric conductivity.The appearance of the in-terface is in the form of sinusoidal wave without swirl zone,Elements Pb and Fe diffuse mutually and the content of Pb reduces quickly from interface to steel while the content of the Fe reduces slowly from interface to lead with interdiffusion depth by micromagnitude.The structure of the contact surface is composed of microcry stalline iron and microcrystalline lead.
