Mechanical Alloying of Ti–Fe Alloys Using Severe Plastic Deformation by High-Pressure Torsion

Abstract

Alloys of the Ti–Fe system with an iron content from 5 to 90 wt % were synthesized from elemental powders using mechanical alloying in Bridgman anvils. The phase composition and structure of the obtained alloys have been studied by X-ray diffraction and transmission electron microscopy. It was shown that grain size decreases with increasing both the iron content in the alloy and the degree of plastic deformation.
