The hot deformation behavior and microstructure of AZ31 and AZ61 alloys processed by the hot-rolled technique were investigated over a strain rate range from 1×10⁻⁴ to 1×10⁻¹ s⁻¹ and temperatures ranging from 350 to 500 °C. Alloys were manufactured by melting and casting, and then hot-rolled at two temperatures of 350 and 450 °C. Tensile test revealed elongations of over 300% in the two alloys. The highest elongation value of 321% at a strain rate of 3×10⁻³ s⁻¹ was achieved in the AZ61 alloy with a hot-rolling temperature of 350 °C. The hot tensile tests showed that there are some differences in ductility between the AZ31 and AZ61 alloys with the same rolling process specifically at low strain rates. A small enhancement in ductility is found using a lower temperature for hot-rolling at 350 °C compared to 450 °C due to improved grain refinement. It is suggested that the dominant deformation mechanism was glide controlled dislocation creep based on the stress and grain size exponent, and activation energy.
