Abstract
Method of selection of initial elements and prediction of phase composition of the dispersion-strengthened copper is described. Technology of manufacture of the material using the method of a mechanical alloying is optimized. Phase composition, structure and properties of the produced material are examined and optimum conditions of the resistance welding with electrodes made from this material are established. It is shown that the application of the dispersion-strengthened copper provides increase in life of products by 2-3 times
Keywords: mechanical alloying, dispersion-strengthened materials, transformations, composition, structure, properties, resistance welding electrodes, life
