A NEW METHOD FOR THE PREPARATION OF SUCCESSIVE REPLICAS FOR USE IN ELECTRON MICROSCOPY,

Abstract

A new method is described for making negative carbon platinum replicas of a selected area. Location of the area to be replicated is accomplished with a micrometer mechanical stage on an optical microscope. A collodion matrix is then formed on a replica grid and the entire assembly is dry stripped with tape. This process does not disturb the specimen surface, even after many replications, which enables the method to be used in the study of the changes in surface structure during mechanical deformation. Several examples of the process are given by the micrographs of the surface damage of aluminum single crystals and 4340 steel specimens subjected to a fatigue stress. (Author)
