Abstract

Titanium alloys are widely used in modern engineering. The ensuring of property of articles and designs during their service is one of the most important problems. It is known that mechanical properties of metals and alloys are determined by their microstructure, formed in a process of thermomechanical treatment according to a history of strain and conditions of a thermal effect. The processing of the required properties of an alloy is an important and difficult task. Its decision assumes comprehensive study of the alloy strain history and determination of an effect of a complex loading that takes place almost in any real technological process. However, as a rule, investigations devoted to this question consider only results of uniaxial loading. This paper presents the results of experimental studies of the influence of a deformation path on changes in globular and lamellar structures of the two-phase titanium alloy Ti-6.5Al-3.5Mo-1.6Zr-0.27Si.
