Stress-induced transformations during the compression of a Ti-1033 alloy

Conference Paper


Abstract


  • A near-B Ti-10V-3A1-3Fe (wt.%) alloy containing different a phase fractions after thermo-

    mechanical processing was compressed to 40% reduction. Detailed microstructure evaluation

    was carried out using high resolution scanning transmission electron microscopy and electron

    back-scattering diffraction. For the first time, deformation-induced B - a" and B - transformation products together with {332}{113}B and {112}{111}B twinning systems were

    simultaneously detected in a metastable B alloy containing an a phase. The effects of strain rate and B phase stability on the preferential activation of these reactions were analyzed. With an increase in B phase stability, stress-induced phase transformations were restricted and {112}{111} twinning was dominant. Aleternatively, less stable B conditions or higher strain rates resulted in the dominance of the {332}{113}B twinning system.
