摘要：

The effect of an internal stress on the formation of stacking fault tetrahedra is examined in a Cu-Fe alloy containing coherent γ-Fe particles. Localization of the formation of stacking fault tetrahedra was found around the γ-Fe particles. This is attributed to the development of vacancy-rich regions around them due to formation of inhomogeneously distributed interstitial clusters. Another example of a local stress effect examined is the formation of a linear array of stacking fault tetrahedra. It is shown that the strain field due to the pre-formed stacking fault tetrahedra brings about directional preference in the vacancy flow to induce such an alignment. © 1990 Taylor & Francis Group, LLC.
