Deformability of cast Mg-2,5Nd-0,6Z alloy (%, wt) has been analyzed under isothermal rolling at 250 and 300 ºC. It was established that a good quality sheet could be processed at 300 ºC only. It is shown that the better alloy deformability at that temperature is conditioned by more activated recovery of it structure.
