Roik O. Experimental investigation and analysis of metal melts structure by methods of reverse Monte Carlo and Voronoi-Delaunay

The thesis is devoted to study of one- and two-component metal melts structure. The procedure of disordered systems structure investigation on the basis of models reconstructed from experimental structural factors by means of reverse Monte Carlo method have been elaborated and tested. It have been established, that the structure of liquid metals Fe, Co, Ni, Ag, Cu, Na, K is formed on the basis of nanometric size clusters making by faintly misshapen tetrahedrons and quarter of octahedrons. Structure of liquid Ga, Sn, Ge is characterized by a micro heterogeneity. The detailed analysis of local structure of Co-Si melts have been realized on the basis of X-ray diffraction experiment.
