Limit values of the normalized Cockroft – Latham criterion for different range of temperature and strain rates may be determined by using the comparative method for the uniaxial tensile test of notched specimens. Uniaxial tension of notched specimens was performed on a multi-function metallurgical process simulator, Gleeble 3800. In order to determine the actual values of the normalized Cockroft - Latham criterion, theoretical studies of the notched specimen tension test were also conducted. The hot tensile deformation and the fracture behaviors of the AZ31 magnesium alloy were studied with the temperature range of 350 – 450°C and strain rates 0.1, 1.0 and 10.0 s-1.Keywords: magnesium alloy, fracture, normalized Cockroft – Latham criterion, FE modeling
