摘　　要：采用普通热轧实验研究了400-550℃终轧温度对AZ31镁合金织构和成形性能的影响。结果表明：提高终轧温度可有效弱化基面织构，提升镁合金室温成形性能。终轧温度从400℃增加到550℃，基面织构强度降为3．1，它的埃里克森值从3．7增加到6．3。结果能为提高镁合金室温成形性能奠定理论基础。The effects of finishing rolling temperatures （400-550 ℃） on texture and formability of AZ31 magnesium alloy sheets were investigated by experiment of ordinary hot rolling. The results show that： by increasing the fmish rolling temperature, the basal texture can be effectively weakened and the formability of magnesium alloy at room temperature can also be improved. By increasing the finish rolling temperature from 400℃ to 550℃ ,the texture strength reduces to 3.1, and the Erichsen value increases from 3.7 to 6.3. The results lay a theoretical basis for improving the formability of magnesium alloy sheet at room temperature.
