摘要：
Mechanical properties of aluminum foams are influenced by the properties of their based materials and cellular structure. In the present paper, in-situ TiB2 reinforced aluminum matrix composites fabricated by melt reaction method were used to prepare aluminum foams, and the influences of in-situ particles on mesoscopic cellular structure and compressive deformation behavior of aluminum based foams were studied. The cellular structure was characterized by micro focus X-ray computed tomography (CT) and the results indicated that addition of TiB2 particles led to an increase in density of cell size simultaneously, and form a uniform cell structure with long and straight cell walls. Quasi-static compression tests showed that the compressive strength of aluminum foams increased over 40% compared to Al-Ca foam when 5.0% or 10.1% TiB2 reinforced aluminum matrix composites were used as based materials. The deformation behavior of foam specimens transformed from elastic-plastic to elastic-brittle failure mode as the content of in-situ particles increased. Comparison to the thermotical models for closed cell foams demonstrated that the increase in compressive strength of aluminum foams fabricated with in-situ particles reinforced aluminum matrix composites was resulted from the improvement in mechanical property of cell wall material by in-situ particles and the improvement in the cellular structure. © Editorial Office of Chinese Journal of Rare Metals.
