AZ91 镁合金被水花形成准备。扔水花的合金与在 350 ° C 的 80% 减小是随后热转动的。as-spray-deposited 和热转动的合金的微结构特征被光显微镜学检验，扫描电子显微镜学和 X 光检查 diffractometry。形成水花的 AZ91 镁合金举办的结果表演与当演员组铸块锭相比，有不太金属间化合的阶段 Mg17Al12 的更好的微观结构由于快冷却和形成过程的水花的团结率在矩阵分散了，并且，因此出现的优秀可使用性。它能与为在更低的温度(330 360 ° C ) 的一张通行证的将近 20% 减小是热转动的，并且全部的减小能在退火以前到达 50% 。在合适的 thermo 机械的处理以后，形成水花的 AZ91 镁合金展出突出的机械性质。

英文摘要：

AZ91 magnesium alloy was prepared by spray forming. The spray-deposited alloy was subsequently hot-rolled with a 80% reduction at 350℃. The microstructural features of the as-spray-deposited and hot-rolled alloy were examined by optical microscopy, scanning electron microscopy and X-ray diffractometry. The results show that the spray-formed AZ91 magnesium alloy has, compared with the as-cast ingot, a finer microstructure with less interrnetallic phase Mg17Al12 dispersed in the matrix due to fast cooling and solidification rates of spray forming process, and, therefore showing excellent workability. It can be hot-rolled with nearly 20% reduction for one pass at lower temperatures （330-360℃）, and the total reduction can reach 50% prior to annealing. After proper thermo-mechanical treatment, the spray-formed AZ91 magnesium alloy exhibits outstanding mechanical properties.
