摘要
ZK60(Mg-Zn-Zr) alloys experience variation of precipitates during aging. The frequency and size of rod- and disk-shaped precipitates change with aging. The effect of aging on texture evolution during warm rolling of ZK60 was investigated. Some difference was found between the texture evolution of solution heat-treated (T4) and artificially aged (T6) samples. The Aged samples had more texture variations along the thickness direction than solution heat-treated samples. The intensities of basal fibers were lower during asymmetric rolling than during symmetric rolling, although the initial intensities increased during both rolling processes. The decrease in basal fibers by asymmetric rolling was clearer at a lower temperature of 448 K (175 A degrees C) than at 498 K (225 A degrees C).
