Abstract

Comparison of mechanical properties for deformed titan obtained by different technological schemes of deformation was realized. It is shown that the titan received by methods of intensive plastic deformation, has considerably more high coefficient of the linear hardening. Temperature dependence of this parameter practically coincides with temperature dependence of yield strength.
