Abstract
An application of neutron irradiation-induced coherency strain control is described. The mechanical properties of pairs of single crystals of Cu-1 wt.%Fe-differing only in the state of coherency of the particles-are compared. It is found that, when the particles are sufficiently big for coherency control to be effective, the alloy yields by the Orowan mechanism and the yield stress is independent of the state of coherency. When the particles are smaller the yield stress is controlled by modulus differences between particles and matrix. The work hardening rates are always low. This, together with other observations, suggests that the particles do not transform to martensite to any great extent.Keywords
