An Evaluation of the Creep Properties of an Al2O3/Ni3A1 Composite and the Effect of Disorder on Mechanical Properties
Keyword(s):
ABSTRACTOrdered Ni3A1 alloys and their composites are attractive materials for elevated-temperature structural applications due to their many favorable properties. The addition of alloying elements can significantly lower the Ni3Al order-disorder transition temperature and also result in the formation of a Ni solid solution. As the percentage of Ni solid solution increases, the composite's room-temperature flexural strength increases. The effect of rocessing parameters on the material's microstructure is discussed. The complex matrix microstructure also has a significant effect on the composite's creep properties. Normal power-law creep was exhibited by the composite material when tested in compression.
