High-purity elements (magnesium, aluminum, silicon, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, germanium, zirconium, niobium, molybdenum, palladium, silver, indium, tin, tellurium, neodymium, hafnium, tantalum, tungsten, rhenium, platinum, gold and lead) were processed by high-pressure torsion and subsequently evaluated by Vickers microhardness measurements. The hardness at the steady state was expressed as a unique function of atomic bond energy, specific heat capacity, specific latent heat of fusion, linear thermal expansion coefficient and activation energy for self-diffusion.
