• Point defect clusters at a twin boundary in pure aluminum are observed by transmission electron microscopy. At the coherent twin boundary, characteristic triangular loops of the vacancy type are formed in quenched specimens, while loops of the interstitial type are formed in electron-irradiated specimens. The direction of the triangles of the vacancy loops is opposite to those of the interstitial loops. These facts can be explained as arising from the difference in the atomic arrangement of the second nearest-neighbor layers around the dislocation loops. It can be concluded that whenever a faulted loop is formed on a stacking fault, the loop is triangular. During electron irradiation of a boundary which contains a vacancy loop, the vacancy loop grows or shrinks depending on the environment around it, while an interstitial loop always grows.
