Abstract:A thermodynamic modeling of the Me-B-C-O (Me = Ti, Zr, and V) system with the use of the ASTRA-4/pc software was performed. The effects of the pressure (10?4–10?2 Pa), temperature (773–1473 K), borating component composition, and the role of B2O3 on the phase relations were discussed. Isothermic and isobaric sections of the MeO2-B2O3-C (Me = Ti, Zr) systems were plotted. Layers of McB2 on carbon steel-45 were formed under conditions of electron beam heating.
