This article presents the results of thermogravimetric and differential scanning calorimetric (TG/DSC) analysis of the products of the titanium – V₀.₆Mo₀.₄ alloy system. The obtained products demonstrated high thermal stability in an air atmosphere up to a temperature of about 500 0C. In this range, no significant mass changes were observed, indicating the absence of decomposition or oxidation. The main exothermic effect, recorded at 6190C, is accompanied by an increase in the sample mass, which indicates the intensive oxidation of carbide components with the formation of TiO₂, V₂O₅, and MoO₃ oxides
