摘　　要：利用基于Al-Ti-B4C系热爆式燃烧合成反应制备了泡沫铝。调整原料摩尔配比,研究原料配比对燃烧合成反应的影响。通过对燃烧产物进行孔结构分析,发现Al、Ti及B4C原料摩尔配比为18∶4∶1及23∶4∶1时,孔隙率大且燃烧温度较高;对燃烧产物进行SEM分析,发现热爆式燃烧合成反应制备的泡沫铝中存在大量微孔。该体系热爆式燃烧合成反应制备泡沫铝的试验研究,为下一步利用该体系自蔓延式燃烧合成反应制备泡沫铝奠定了实验依据。Aluminum foam was prepared by the Al-Ti-B4C system heat explosion type combustion reaction.The effect of the ratio of raw on aluminum foam was researched.The analysis of pore structure found that when the molarratio of Al,Ti and B4C is 18：4：1 and 23：4：1,the porosity of product and combustion temperature is higher.There are a large number of micropores （micron）can be found in the combustion product by SEM Scan.The experiment research on aluminum foams prepared by this system heat explosion type combustion synthesis reaction lay the experimental basis for aluminum foams prepared by this system self-propagating type combustion synthesis reaction.
