Origin of copper precipitation strengthening in steel revisited

Evaluation of the various sources of strengthening of ferritic steels by body-centered cubic (bcc) Cu alloy precipitates using the usual models eliminated misfit and modulus mismatch as the sources. The strengthening was attributed to the details of forcing a dislocation through a bcc Cu precipitate...
