Alternative Technology for Manufacturing Rod–Wire Products from AK12 Silumin

Resumo

We develop and test a flow diagram of the process of manufacturing of rods and wires from graded loose chip wastes of eutectic silumin based on the use solely of the procedures of plastic working and heat treatment. In its realization, we use the method of combined rolling–pressing of preliminarily briquetted chips with subsequent drawing of pressed rods. The possibility of getting semifinished and finished products with higher levels of strength and plastic properties as compared with cast silumin is demonstrated. The specific features of formation of the structure of the material after the realization of individual stages of the general flow diagram are indicated.
