Abstract The multiple regression analysis method is used for quantitative estimation of the complex of factors affecting the mechanical properties of the thermomechanically strengthened rebars; this method permits selecting the most valuable quantities characterizing σy, σuts, and δ and assessing the degree of influence of separate elements on these properties within the standards and technological parameters of strengthening. A mathematical model of formation of the strength and plastic characteristics of thermomechanically strengthened rebars is developed, which allows predicting their final mechanical properties. The analysis of the derived relations shows that the established character of the dependences, determined by the signs of coefficients, responds to the physical meaning of a technological factor at consideration.
