Modeling and analysis of the structure of the 35Ni-57Mn-8C melt

The 35Ni-57Mn-8C melt has been studied at 1300, 1400, and 1500°C using X-ray diffraction. From the obtained experimental curves of the structure factor the structural models of the melt has been reconstructed at all temperatures under study using the Reverse Monte Carlo (RMC) method. The local structure of the resultant models has been examined employing the Voronoy-Delaunay statistical and geometrical method. Structures of the 92Ni-8C, 38Ni-62Mn, and 35Ni-57Mn-8C melts have been compared. Carbon atoms in the 35Ni-57Mn-8C melt have been shown to have an increased mobility as compared to the 92Ni-8C melt.
