High Temperature Deformation Processes and Strengthening Mechanisms in Intermetallic Particulate Composites

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.
