    Research output: Contribution to journalJournal articleResearchpeer-review


    A study of the Bauschinger effect in pure copper shows that by comparison with dispersion hardened copper the effect is very small and independent of temperature. This suggests that the obstacles to flow are deformable. A simple composite model based on this principle accounts for the data semi-quantitatively and also accounts for the stored energy of cold-work. An interesting feature of the model is that it shows very clearly that, although dislocation pile-ups may exist, the flow stress of the composite is entirely due to the resistance to dislocation motion in the tangles of forest dislocations.
