Structure, Phase Transformations, and Diffusion


Quenched titanium–ruthenium alloys containing 0.25–4 at % ruthenium have been studied using X-ray diffraction analysis, optical metallography, transmission electron microscopy, and microhardness measurements. It has been found that, during the quenching of the alloys containing 0.25, 0.5, and 1 at % ruthenium, a polymorphic β → α transformation occurs with the formation of a two-phase (α + β) structure. In Ti–1.5 at % Ru and Ti–2 at % Ru alloys, a martensitic β → α″ transformation occurs. The quenched Ti–3 at % Ru alloy has a β + ω structure. The complete stabilization of the β phase takes place in the alloy with 4 at % ruthenium. In the electron-diffraction patterns of alloy containing 4 at % ruthenium, diffuse scattering that indicates the formation of ω-phase-related displacements in the locations of atoms has been observed.
