A technology for producing a Ti–26Nb alloy is developed. The effect of heat treatment conditions on the structure and the phase and chemical compositions of ingots is studied. Optimum homogenizing annealing conditions (900°C, 12 h) are found, which leads to the formation of a completely recrystallized structure. After melting, the alloy is found to be represented by a mixture of 66.5 vol % βm-Ti and 33.5 vol % α'-Ti with the bcc and orthorhombic crystal lattices, respectively. After annealing, the phase composition is shown to change to the continuous β phase with traces of the ω phase, which increases the microhardness of the alloy. After annealing, a homogeneous distribution of chemical elements over the entire volume is observed. The oxygen, nitrogen, carbon, and sulfur contents correspond to standard specifications for titanium alloys. [ABSTRACT FROM AUTHOR] |
