抄録

  We produced AZ31B magnesium alloy sheet by our semisolid casting method to cast slurry produced using an inclined cooling plate into the twin-roll. In this paper, the sheet obtained by this process was examined for texture, roll workability and Erichsen value compared with the chill cast plate and commercial AZ31B sheet. The results are as follows. The microstructure of continuously cast sheet exhibits fine grains of primary Mg-crystals. A (0001) pole figure of the continuously cast sheet confirms that the crystal direction was random and there was little rolling anisotropy. Influence of different heating temperatures on accumulative rolling reduction of the twin-roll cast sheet was not appeared by different roll directions versus the casting direction. The accumulative rolling reduction of the twin-roll cast sheet is higher than chill cast sheet in case of heating temperature of 473 K or less. The Erichsen test indicated excellent value.<br>
