Abstract
A technique is described in which use is made of the slit type electron microscope specimen carrier for replicating successively the same spot on a metal sample. The main advantage is that no specialized apparatus is required. By using the slit type specimen carrier a relatively large undisturbed field of view is obtained. A series of electron micrographs showing the formation and growth of slip lines on an α‐brass single crystal is used to demonstrate the capabilities of the method.
