Slices 100 to 600 Å thick were cut in an ultramicrotome from a variety of nonferrous metals and alloys and examined in an electron microscope. Microtoming appears to introduce high densities of dislocations which anneal out rapidly in the case of low-melting-point materials. High densities of “fault bands” are observed in certain grains of copper and silver. Particles as small as 7 to 20 Å thick by 70 Å or more long may readily be detected, together with the coherency strains round them. Fine holes may also be examined.
