粉末冶金泡沫铝的研究进展

Progress of the Research on Aluminium Foam Made by Powder Metallurgical Route

泡沫铝是一种新型的超轻多功能材料。粉末冶金发泡法因能制备异型泡沫铝和泡沫铝芯三明治复合结构．可满足汽车、航天、航空和军工等领域的需求，已成为当前泡沫铝研究的热点方向.本文介绍了国内外粉末冶金泡沫铝方面的研究现状，指出了现存问题。并展望了今后的发展趋势。

Ultra - light aluminium foam is a kind of muhifunctional material. Aluminium foam and aluminium foam sandwich （AFS） with 3 -dementioanal shape can be made by powder metallurgical foaming method, which has found wide application in the fields of automotive industry, aviation, spaceflight and war industry. In the present paper, the researches on aluminium foam made by powder metallurgical route are reviewed, the existing problem is indicated, and the future development is prospected.
