摘要：

Production technology of an Ti-10Nb-(1-3)Mo alloy has been developed. The effect of heat treatment conditions on the structure, microhardness, and impurity composition of ingots is studied. The optimum conditions of homogenizing annealing (950 degrees C for 12 h), which results in leveling the chemical composition and the formation of completely recrystallized structure, are determined. After annealing, an increase in the microhardness and the homogeneous chemical element distribution over the entire volume takes place. After melting, the alloys comprise the alpha'/alpha"- and beta-Ti phases; after annealing, the alpha-, beta-, and omega-Ti phases are present. The oxygen, nitrogen, and carbon contents correspond to regulations for titanium alloys. According to fractional gas analysis (FGA) data, the titanium oxide content dominates over the niobium and molybdenum oxide contents.
