Al matrix syntactic foams with additional Al particles embedded were fabricated by the pressure infiltration method. Their compressive behavior was studied and compared with that or the plain syntactic foams. With the introduction of Al particles, the ductility of the syntactic foams is significantly increased and the compressive strength increases by up to 30%. As a consequence of the increased ductility and plateau strength, the specific energy absorption capacity is increased by up to 80%, reaching 50.6 kJ kg(-1). (C) 2009 Acta Materialia Inc.
