Abstract

The manufacturability of a gadolinium-alloyed intermetallic VIT5 titanium ortho alloy during deformation at temperatures of 800–1100°C is studied. The mechanical properties and the structure of plates rolled according to two deformation regimes are analyzed. The effect of the morphology of the Ti2AlNb ortho phase on the strength, plastic, and high-temperature properties of the alloy is investigated. The formation of a specified structure is shown to provide a high level of plasticity and high-temperature strength. The relative elongation at 20°C is 7.0%, the tensile strength at 700°C is 950 MPa, and the long-term tensile strength at 700°C for 100 h is 300 MPa.

Notes

  1. The test temperature range was chosen taking into account the conditions of deformation of VTI-4 ortho alloys. The samples were not compressed at higher temperatures, because the alloy has a high technological plasticity and its behavior is similar to that of REE-free ortho alloys at temperatures above 1115 ± 5°C (in a single-phase β/B2 region) [23].
