An influence of slag refining on the structure and mechanical properties of the brass CuZn39Pb2

The results presented in the dissertation show the influence of a kind and concentration of the flux added during the process of the lead brass smelting on its structure, chemical composition and mechanical properties—hardness and strength. A positive refining, structure, mechanical properties, brass influence of the refining and modification process manifested in an improvement of mechanical properties as well as an increase of the structure, chemical composition and mechanical properties homogeneity in the entire volume of the ingot has been proven. The influence of the flux concentration on the structure and mechanical properties of the alloy was determined. The optimal flux concentration improving the tested properties was established.
