"The paper deals with study of segregation (microsegregation) behaviour of selected elements in the course of crystallization and solidification of Ni-based superalloy IN 738LC. The purpose of this paper is investigation of microsegregation and chemical heterogeneity of cast and heat treated IN 738LC Ni-based superalloy on the basis of experimental measurement of concentration distribution of the constituent elements in the dendrite core and interdendritic regions. The concentration data sets of aluminium, titanium, chromium, cobalt, nickel, niobium, molybdenum, tantalum and tungsten were measured in 101 points on the 500 m long line segment (the distance between individual points was 5 m). This line segment crossed several dendrites, i.e. several dendrite cores and interdendritic regions. The concentration data sets of these nine elements were determined using a microanalytical complex JEOL JXA-8600/KEVEX Delta V, Sesame and the method of energy dispersive X-ray spectroscopic microanalysis (EDS).
