| description | The paper presents preliminary results of research on the use of certain smelting slags in the process of modification of casting alloys, leading to a change in the structure of these alloys and improvement of their mechanical and operational properties. The positive effect of ground copper slag with a fraction below 0.1 mm on the effect of modifying the hypoeutectic silumin AlSi7Mg towards changing the morphology of coarse-grained eutectic to fine-dispersive was demonstrated. The modifying effect also applies to the pre-eutectic α phase and results in the formation of additional crystallization sites (nucleation process), which was demonstrated by the thermal ATD solidification analysis, showing an increase in the temperature Tliq and TEmax. The positive and noticeable influence of the mixture of copper and steel slag on the surface modifying effect of fragmentation of the structure was demonstrated in casting nickel superalloy IN-713C. Based on the results of research conducted so far on the modifying effect of cobalt aluminate, a hypothetical model of the impact of reduced metallic components of the applied metallurgical slags on the nucleation process and shaping of the microstructure of nickel alloys was developed. |
