Concentration Redistribution of Alloying Elements in Pseudo-Alpha-Titanium Alloy under Elastoplastic Deformation

Abstract

The paper studies redistribution of alloying elements (Al, V, Mo) in the pseudo-alpha-titanium structure under graded stretching until destruction of the sample. Local sections of the titanium structure and of the fracture surface have been scanned by electron microscopy and X-ray microanalysis. The change in the chemical and phase composition of the alloy has been compared with the initial state stimulated by deformation impact. The structural-phase state of the material under high plastic strains is metastable, fixed by the system of deformation defects of the crystal lattice.
