Abstract

Variations in the grain size and basal texture in magnesium hot-rolled in the temperature range 570-770 K have been studied and compared with those observed in specimens hot-rolled at 570 K and annealed at different temperatures in the range 570-770 K, In specimens hot-rolled temperatures higher than 670 K, a rapid increase in grain size and a weakening in basal texture have been observed. The yield stress of the specimen is lower than that predicted by the Hall-Petch relation and this result is interpreted in terms of the reduced basal texture. The dependence of yield stress on grain size in magnesium hot-rolled at different temperatures lower than 670 K matches with that observed in specimens annealed at different temperatures.
