In the AI-Cu system precipitates of the intermediate 0' phase generally nualeate at low-angle boundaries and precipitates of the equilibrium 0 phase form at high-angle boundaries. A few exceptions oocur where 8' precipitates form at high-angle boundaries and these have been studied by transmission e
The elevated temperature creep properties of a fine grained copper alloy (CDA 638) was investigated between 673 and 798 K at strain rates ranging from lo-' s-' to 2 x lo-\* s-'. The mechanical data were analyzed in order to establish the stress, temperature, and grain size dependence of the strain r

A~traet--Temperature change tests have been done during steady-state creep of polycrystalline aluminum to obtain some fundamental information on the activation energies for parameters related to hightemperature deformation. By the direct passing of a current through a specimen, a temperature increas
