| 摘 要： | 采用一套新颖的反重力渗流装置制备开孔泡沫铝。研究表明,采用反重力渗流法所制备的泡沫铝,表现出优良的力学性能且几乎没有渗流不足与渗流过度的缺陷;泡沫铝中的空隙度对其力学性能的影响很大,泡沫铝的屈服应力与平台应力均随孔隙度的降低而升高;升高预热温度与保压压强可有效降低泡沫铝中的空隙度。

| Abstract: | A novel counter-gravity infiltration casting device and corresponding fabricating process for producing open-celled aluminum foams were presented. The experimental results show that defects such as insufficient or excessive infiltrating can hardly be found in the foam samples prepared by counter-gravity infiltration casting. The foam materials exhibit excellent mechanical properties. The void content strongly affects the mechanical properties of aluminum foams. The yield stress and plateau stress significantly increase with the decrease of void content. Raising pre-heating temperature and increasing packing pressure are effective to lower the void content in aluminum foams. |
