Analysis of Solidification Parameters and Macrostructure of IN-713C Castings after Complex Modification

Open access


The paper presents a research results concerning impact of volume modification (ceramic filter containning cobalt aluminate and hafnium powder) and simultaneous surface and volume modification on solidification and stereological parameters of macrostructure of castings made from post-production scrap of nickel superalloy IN-713C. Research included investigation of the influence of chemical composition on the temperature Tliq i Tsol and evaluation of following macrostructure parameters: the number of grains per mm2, average grain area and shape coefficient. Results indicate high influence of carbon content on Tliq. Macrostructure of sample castings indicate positive effect of surface and volume modification, however impact of surface modification is more pronounced.
