“…Nowadays, the concept of aluminum and molybdenum equivalents for alloying elements and impurities, which characterizes the chemical composition of titanium alloys, has received widespread use in science and practice [1][2][3][4][5][6][7]. In order the assess the ultimate tensile strength of α-, near α-, and α+β alloys at room temperature based on aluminum and molybdenum equivalents, B.A.…”

This study contains the results of statistical studies of strength of sheeted products and bars made from α-, near α-, and α+β titanium alloys based on their composition. Based on summarizing the literature data, we have studied the ultimate tensile strength after mill annealing of 30 serial and experimental alloys at testing temperatures between 20 and 600°C. We have also substantiated the possibility to evaluate the tensile strength of semi-finished products using the strength equivalents (such as aluminum and molybdenum) of alloying elements and impurities at various temperatures. We have put forth models that help to predict the ultimate strength of titanium alloys based on their composition and the operating temperature with a confidence level of 0.95 and statistical errors comparable with the regulated spread.
