dc.description.abstractThe contribution deals with prediction of tensile properties based on measurement of microhardness. First of all, the database of stress - strain, σ-ε vs. hardness data was created. Tensile strength, yield strength, ductility and parameters of Ludwik-Hollomon equation σ = σ0+kεn ; k, n were correlated with hardness. Various hardness values found in literature were recalculated to Brinell hardness. In tensile testing measured σ-ε curves were compared with that obtained from the correlation. The investigated materials were API 5 L grade steels - X70 after different deformation levels. The results give good agreement between compared data. The most significant difference between estimated and measured curve is in area of yield strength, because of Lüders deformation on investigated steel. © (2014) Trans Tech Publications, Switzerland.en
