Abstract The correlations between tensile properties (yield strength, ultimate tensile strength and uniform strain) and indentation hardness are studied for two types of Al-Zn-Mg alloys. The reasons why Tabor's equations do not well fit the experimental data when the strain-hardening coefficient is larger than 0.3 are discussed. New equations for the determination of tensile properties from hardness measurements are theoretically derived and found to be in excellent agreement with the experimental data for Al-Zn-Mg alloys. The equations areT u=(H v/c 2)[4.6(m−2)] m−2 and σy=(H v/C 2)1-(3−m〉 ) +25 (m−2), whereT u andσ y are ultimate tensile strength and yield strength,H v is Vicker's hardness number,m is Meyer's hardness coefficient,E is Young's modulus,c 2 is a constant about 2.9 in magnitude. In these equationsT u,σ y,H v andE are all expressed in kg mm−2.
