摘要：
In situ TiC-TiB2 reinforced Al foams with excellent mechanical properties were fabricated successfully via a novel method by the combination of Ti-B4C self-propagating reaction and melt processing technique. The results showed that the interfacial bonding of TiB2/Al and TiC/Al was excellent and the in-situ TiC-TiB2 reinforced Al foams exhibited an superior mechanical properties and energy absorption capacity as well as uniform deformation simultaneously. Compared with pure Al foams, the compressive strength and energy absorption capacity of the in-situ TiC-TiB2 reinforced Al foams improved by about 149% and 168%, respectively. (C) 2020 Elsevier B.V.
