They are presented in the form of isothermal and vertical sections, projections of liquidus and solidus surfaces, melting diagrams, and reaction schemes after Scheil. Within the CALPHAD procedure, thermodynamic descriptions of the ternary system Mo–Fe–B and the boundary binary Fe–B were obtained in the whole range of compositions. Thermodynamic properties of binary melts Ba–Sn, Sb–Sr, Gd–Sn, Ho–Sn, Bi–Eu, Ge–Yb, In–Pr, In–Nd, In–Ho, Al–Gd, Cu (Ag, Au)–Yb, Cu (Ag, Au)–Ge and ternary melts Gd–Ni–Sn, Ge–Cu (Ag, Au)–Yb, Al–Gd–Mn and In–Ho (Nd, Pr)–Ni were estimated for the first time. Four new ternary compounds were identified, their crystallization paths and stability parameters were established. The thermal and deformation stabilities of the orthorhombic martensite of Ti92,5Nb5Mo2,5 composition were studied, a material with a low modulus of elasticity, 66 GPa was obtained by means of doping with silicon and zirconium and quenching. The kinetics and products of oxidation have been studied for Ti–Nb–Mo alloys. Product Description popup.authors Ivanov Mykhailo I. Artyukh Svitlana Y. Bykova Svitlana V. Bulanova Maryna V.
