【 摘 要 】

Thermal stability of PM Al/5%NiA1 composites has been studied by exposure at 500 degrees C up to 24 h. NiAl intermetallic particles were employed as-received and after pre-oxidation at several temperatures. The optimal oxidation condition was determined based on its ability to delay interfacial reactions and prevent debonding at the metal/reinforcement interface. (c) 2005 Acta Materialia Inc.
