Bondarchuk Vadim. High-temperature creep of titanium alloys with different microstructure. Manuscript. The thesis for the degree of Candidate of physical and mathematical sciencies on speciality 01.04.13 Physics of Metals. Institute of Metal Physics, Kyiv, Ukraine, 1999. The thesis is aimed at investigation of high-temperature deformation and creep of titanium alloys including commercial pure titanium VT1-0, near-, ()- and near- alloys. The influence of an initial microstructure and testing conditions (stress, temperature) on high-temperature strength of these materials is studied. It is shown that there is some temperature On for titanium alloys, at which an abrupt decrease of their strength and creep resistance occurs. This decrease is caused by a change of deformation mechanism due to an activation of diffusional processes connected with the beginning of diffusional transformation. Above On the deformation of titanium and its alloys is controlled by a diffusional recovery. It is found that Tc does not depend on an initial microstructure of the peculiar alloy and is determined only by its chemical composition. Below On, rapid heat treatment of titanium alloys ensures higher high-temperature strength in comparison to standard heat treatments. Above On, influence of an initial microstructure of titanium alloys on strength and creep resistance depends on the conditions of their exploiting. Key words: titanium alloys, microstructure, hardness, strength, activation energy of deformation, deformation mechanism, high-temperature creep, creep mechanism, creep resistance, high-temperature strength.
