Abstract

Changes in the structure, phase composition, chemical composition, Vickers microhardness, and contact modulus of elasticity of a high-strength titanium α + β-alloy of the VST2 martensitic class during quenching after heating in the 700 – 1000°Ñ range were studied using the methods of optical microscopy, XRD phase analysis, microindentation, and thermodynamic calculations in ThermoCalc. The experimental data were in good agreement with the results of thermodynamic calculations. Arelationship between changes in the microhardness and contact modulus of elasticity of VST2 alloy, quenched from 700 – 1000°C, and the structure and phase composition of the alloy during quenching was established.
