Abstract
The aim of this article is to compare the influence of the phase architecture on the mechanical properties of two interpenetrating MMCs with same metallic and ceramic phases and similar phase contents. One of the composites was fabricated by infiltrating freeze-cast alumina preforms, while the other composite was fabricated by infiltrating open porous alumina foam. Tests were carried out to determine the three longitudinal elastic constants, elastic-plastic flow behavior under compression and mechanism of internal load transfer under compression. Results show that phase morphology has a significant influence on the composite mechanical properties. Highest stiffness and compressive strengths are observed along the freezing direction in the freeze-cast MMC and this result from the significantly higher fraction of load carried by the alumina phase in this MMC type. Foam based MMC shows more isotropic behavior and its properties lie between the longitudinal and transverse properties for freeze-cast MMC.
