Past work has shown that freeze casting is a relatively simple method to create a nacreous material with a polymer matrix. However, computational work (Begley, et al. 2012) suggests that the strength and toughness of such materials can be improved with a metallic mortar if the mortar has a lower strength than the fracture strength of the ceramic bricks. However, capillary forces prevent infiltration of metals into freeze-cast ceramics. Bulk metallic glasses can infiltrate ceramic scaffolds without any added pressure due to reactive wetting, which is a process where the metal reacts with the alumina to create an interfacial layer it readily wets. This study focuses on the effects of ceramic content and infiltration temperatures on the mechanical properties of such materials. The results show that the infiltration temperatures determine the thickness of the intermetallic phase, which in turn affects the mechanical properties of the brick-and-mortar materials.
