This research is to test a combined chemical-technological chain of material production. The tests are made on a 70Cu/30Fe system. The technology consists of: 1-SHS of a cast material of a specific composition and 2-Mechanical and heat treatment, including: continuous swaging, where the workpiece is heated to 850°C and then drawn cold. In this study first used SHS-metallurgy method for producing, in the molten pseudoalloy Cu-Fe system (Cu-70%, Fe-30 wt.%). It was found that the high temperatures melt the SHS provides increased solubility of Cu in Fe. Then, in the crystallization, by decreasing the melt temperature and reduce the solubility limit of copper is released in the form of small dispersed particles. The observed structure is typical only for SHS alloy.
