The work includes studies to determine the significance of the effect of selected technological parameters of moulding and casting conditions on the macrostructure of IN-713C cast nickel alloy. Two-level, fractional 24-1 experiment was carried out, requiring eight experiments. The evaluation covered the number of grains per 1mm2 of the sample surface, the average grain surface area, and the shape index. Macrostructure of test castings indicates a positive effect of combined surface and bulk inoculation treatment, with the effect of surface inoculation prevailing as regards its importance. Statistically significant effect on the number and surface of grains have in descending order: surface modification, bulk modification and temperature of alloy pouring.
