Various pure metals (Al, Au, Ag, Cu, V, Pt, Ni, Fe, Co, Ti, Zr, Hf, Mo) including Cu-30%Zn are processed by high-pressure torsion. Most of Vickers microhardness (HV) values are expressed by a universal plot when they are normalized as (HV/G)(T/Tm) and plotted against εP/G, where G.T./Tm εand P are shear modulus homologous temperature equivalent strain and pressure. resnectively. Deviations to this plot are for Al (99.99%), Ti, Zr, Hf and Cu-30%Zn and for when P is below a critical pressure.
