“…139 These particles are incoherent with the matrix and cannot be cut by dislocations, 33 thereby promoting lower strength values and a high strainhardening rate resulting from the accumulation of Orowan loops around the copper phase particles. As the strain is increased, however, the gradual development of primary shear loops generates intense stress fields around the strengthening precipitates, which are in themselves limited 137 by the activation of a secondary dislocation cross-slip process, thus reducing the strain-hardening ability of the material.…”

“…They were typically equi-axed in shape with faceted sides, although rod shaped particles were frequently present. (18) and Stolz and Pelloux (19 Figure 69 has already been discussed. An additional micrograph of this specimen is shown in Figure 71 with dislocations in contrast.…”

“…Non-shearable obstacles lead to lower UTS and, at low strains, they result in a high strain-hardening rate because of the accumulation of Orowan loops around the strengthening particles. 244 As the strain is increased, the buildup of primary shear loops generates intense stress fields around the strengthening precipitates.…”
