The results of studies on the effect of modification on macrostructure and mechanical properties (hardness, R₀₂, R_m, elongation A₅ and reduction of area Z) of IN-713C nickel alloy, examined on “carrot”- type specimens⁽¹⁾ were presented. One surface-volume modified melt and two volume-modified melts were made. As a reference, the results obtained on non-modified castings were used. A very beneficial effect of the combined surface-volume modification on alloy macrostructure (equiaxial crystals) and mechanical properties was reported. Volume modification produces mixed structure of columnar and equiaxial crystals. The efficiency of modification was additionally enhanced by application of filters made according to the authors’ genuine design. The inoculant used in these filters was cobalt aluminate CoAl₂O₄.
