Abstract
Aluminium foils thinned by acid etching have been examined by transmission electron microscopy. Cellular patterns, 0.2 microns in spacing, havo boen observed superimposcd upon the normal subgrain structure of the metal. The cellular structure resembles patterns observed by other workers on replicas of chemically polished aluminium and interpreted as evidence of crystal misorientation. This communication shows that the cellular structure arises from a surface etching process and bears no relation to the distribution of dislocations in the metal. It is therefore most improbable that a further subdivision of the crystals is revealed.Keywords
