Abstract
Structure of the transition zone in a joint of metals having no mutual solubility was studied. It was determined that surface of the explosion welded Cu-Ta joint is not smooth, but contains protrusions with a size of about 5-10 mm. The transition zone of the joint consists of chaotically distributed non-melted regions of copper and tantalum, as well as zones of local melting of copper containing tantalum nanoparticles 30-50 nm in size. Two processes, i.e. formation of protrusions at the interface and local melting zones, determine stirring of the materials having no mutual solubility.
