- Abstract
The physical and mechanical properties of the joining zone of metal produced by autonomous vacuum brazing of copper M1 on steel billets were determined. During tensile test the fracture of standard specimens occurred always in the copper part. At the same time, the strength properties of brazed copper layer in the initial state exceeded the reference values for wrought and annealed copper M1. The ultimate tear strength of brazed copper layer determined on the special specimens is equal to the temporary rupture strength of steel 20. The investigations of physical characteristics of the joining zone showed that during technical calculations the additional electrical and thermal resistances of the contact zone can be neglected.
