N2 - Using the calculation and experimental techniques, we studied the effect of cold rolling to degrees of 85 and 90% on the structural and textural condition, microdurometric and elastic properties of the following quenched biocompatible β-titanium alloys (in at %): Ti–26% Nb–3% Zr, Ti–26% Nb–5% Zr, Ti–26% Nb–6% Zr, Ti–26% Nb–3% Zr–1% Sn, Ti–26% Nb–3% Zr–1% Sn–0.7% Ta. It is shown that an increase in the degree of deformation at cold rolling promotes the formation of a more pronounced two-component texture {001}β [removed] β, {112}β [removed] β, a growth in the microhardness, and a decrease in the values of the elastic modulus in the plane of rolling. It is established that there is good agreement between the calculation and experimental values of the elastic modulus of these alloys in the quenched and cold-rolled state. The effect of alloying and anisotropic state of the alloys (via the molybdenum equivalent and the Zener anisotropy index, respectively) on the levels of their microhardness, contact elastic modulus E, including the difference in E in different sections of cold-rolled sheet,—is considered. Those compositions of alloys and the modes of deformation are determined that allow one to obtain the lowest values of their own elastic moduli.
