研究了“微织构”对Mg-Al-Zn合金板材拉伸性能和室温拉伸成形性能的影响。通过固溶处理、热轧和后退火，在Mg-Al-Zn合金板材中成功地引入了显微织构。由于拉伸孪生的高活性和基底滑移的施密德因子变化不大，独特纹理分量（与板法向倾斜50°或以上的（0001）极）的比例略有增加，这将极限圆顶高度从5.1 mm提高到7.0 mm，而强度没有损失。这一发现强调了“微织构”设计对于开发具有高强度-成形性协同效应的镁合金板材的重要性。
The effect of “micro-texture” on tensile properties and room-temperature stretch formability of Mg-Al-Zn alloy sheet was investigated. The micro-texture was successfully introduced in the Mg-Al-Zn alloy sheet by solution-treatment, hot-rolling, and post-annealing. The fraction of unique texture component ((0001) poles being tilted by 50° or more from the sheet normal direction) increased slightly, which improved a limiting dome height from 5.1 mm to 7.0 mm without loss of the strength owing to high activity of tensile twinning and little change in the Schmid factor for basal slips. The finding emphasizes the importance of “micro-texture” designing for the development of magnesium alloy sheets with high strength-formability synergy.
