Thermodynamic preconditions of the titanium compounds formation with interstitial elements (C, N, O, B) depending on temperature and pressure of gaseous medium

Abstract

Results of the thermodynamic analysis of the probability of formation of chemical compounds in the «Ti-C-N-O-B» system are presented in this paper. The ranking of the formation of chemical reactions as a function of temperature (T = 100...1200°C) and air pressure (P = 1.33∙10-8...1∙105 Pa) is carried out. It is shown, that titanium will interact with oxygen most actively, forming a interstitial solid solution with the subsequent T = 900°C titanium boride. Reduction of air pressure is not likely to reduce the formation of compounds containing formation of oxides; following the probability, nitrides will be formed, then carbides and up to temperature oxygen and nitrogen. Thus, at the temperature T = 800°C, the available compound B2O2 will be decomposed and will not be formed at the pressure below P = 1.33∙103 Pa.
