Effect of Thermohydrogen Treatment on the Manufacturing and Mechanical Properties of a Heat-Resistant VTI-4 Intermetallic Alloy

详细

The effect of additional alloying of a Ti₂AlNb-based VTI-4 alloy with hydrogen on the structure, the phase composition, and the manufacturing and mechanical properties of the alloy is studied. Hydrogenating annealing is found to favor the formation of a single-phase O structure at room temperature and to increase the deformability of the alloy. The mechanical properties of the alloy subjected to thermohydrogen treatment under different conditions are shown to be comparable with those reached by traditional annealing.
