Abstract:

Research on the high temperature deformation processes and strengthening mechanisms in Intermetallic Particulate Composites is described. Work of the grant included high temperature compression tests of Nl3Al - Al2O3 composites mechanical alloying of Ni3Al Y203 transient deformation studies of the intermetallics Ni3Al, NiAl , NiBe and development of a model of dislocation structure control of plastic deformation. Work during the past year on the high temperature deformation of NiA1 single crystals is also described. Intermetallic Alloys, High Temperature Strength.
