Summary

We investigate the creep behavior of metals strengthened by particles on two differing length scales, namely microscopic dispersoids and macroscopic reinforcements. It is shown that theoretically one expects the combination of the two particle types to result in creep strength far superior to that of materials with only one of the particle types. Finite element analysis supports this theory. Some guidelines for optimal design parameters are given.
