Abstract
The results of investigation of structure of transition zone of aluminium-tantalum joints, having different plane or wavy shape of the interfaces, are presented. Independently of the shape of boundaries, two types of fragmentation were revealed: one of them is similar to fragmentation in explosion, another one - at intensive plastic deformation. The same types of fragmentation were earlier observed also in joints of copper-tantalum having no mutual solubility unlike the aluminium-tantalum. Melting was observed in transition zone of joints being investigated. Structure of melted areas depends greatly on the availability of mutual solubility in metals being welded.
