The paper presents the results of investigations on the effect of modification process on mechanical properties and high-temperature creep resistance behaviour of IN-713C alloy specimens. Two melts modified in volume were made and one melt modified by combined surface-volume technique. A beneficial modifying effect of filters designed according to the authors’ genuine concept has been proved. As a reference, the results obtained on non-modified castings were used. A very beneficial effect of combined modification on the degree of equiaxial grain refinement and increase of R_m and R₀₂ has been reported. Unfortunately, refining of macrostructure obviously deteriorates the alloy high-temperature creep resistance behaviour.
