Structure Formation and Hardening of the Hybrid Material Based on Vanadium and Zirconium Alloys during High-Pressure Torsion

Resumo

A layered hybrid material is prepared by high-pressure torsion of a three-layer (vanadium alloy–zirconium alloy–vanadium alloy) billet. A mixed nanostructure with a highly uniform distribution of zirconium and vanadium alloy regions forms under the chosen severe plastic deformation conditions in the middle layer of the material. The microhardness of this layer increases by a factor of about 2.5 as compared to the initial state.
