Korniyenko K. Phase equilibria in the binary and ternary systems formed by scandium with ruthenium and rhodium

Objects of investigations: binary and ternary systems, formed by scandium with ruthenium and rhodium. Aim of the work: experimental investigation of the phase equilibria and plotting of phase diagrams of the systems Sc-Ru, Sc-Rh and Sc-Ru-Rh; analysis of metal chemistry of binary and ternary systems formed by scandium with platinum metals. The cast and annealed alloys are investigated using the methods of metallography, X-ray, differential thermal, microprobe as well as microdurometrical analyses. On the basis of plotted phase diagrams and established regularities prognoses of phase equilibria in the Sc-Os, Sc-Pt, Sc-Rh-Pd, Sc-Pd-Ir and Sc-Ru-Pd systems are presented for the first time. Areas of usage: physical chemistry of metallic systems, materials science and development of new materials.
