Deformation resistance and structure of a hot-rolled AZ31 magnesium alloy

Popis výsledku v původním jazyce

An experiment leading to obtaining the mathematical model of the mean equivalent stress (MES) of magnesium alloy AZ31 was realized in the laboratory rolling mill. Neglecting of the speed term in the resulting model of MES was possible by a relatively narrow range of applied strain rates, and also by the fact that a close relationship between height strain and strain rate exists. The paper also presents the obtained data, related to the dependencies between deformation process parameters, inhomogeneity and grain size after dynamic recrystallization for the specimens subjected to hot rolling. A significant influence of the deformation temperature on the grain size after recrystallization was identified, while observing lower sensitivity of this parameterto an increased rolling speed.
