Grytsiv A. Phase equilibria in the ternary systems formed by chromium with carbon and d-metals of VII or 3d-metals of VIII groups

Objects of research: phase equilibria in the ternary systems formed by chromium with carbon and d-metals of VII or 3d-metals of VIII groups (Cr-M-C). Aim of work: experimental construction of full phase diagrams of ternary systems Cr-Re-C and Cr-Ni-C; discovering and explanation of relationships of changing of phase stabilities and phase diagrams topologies for Cr-M-C systems. As-cast and annealed alloys were investigated by X-ray phase analysis, electron- and optical microscopy, microprobe, differential thermal analysis and the solidus temperature was determined by Pirany-Alterthum method. Prediction of Cr-Tc-C solidus surface and recommendations as for optimisation of conditions for industrial CCN alloys were presented on the basis of constructed phase diagrams and discovered relationships. Areas of usage: physical chemistry of the metal systems, materials science and development of new materials.
