Abstract
The tensile creep behavior of a series of nickel-copper laminate composites, in which the composition gradients between the 20-μm. m layers were controlled by heat treatment, was evaluated at 500 °C. With annealing, the high-temperature creep resistance increased due to the direct effects of solid solution strengthening within the layers. The results correlated to predictions based on a composite model which approximated the continuous composition gradients as a series of discrete compositional zones.
