Abstract:

An adaptation of the polystyrene-silica technique has been developed for preparing replicas of the surfaces of iron whiskers. By this technique the original whisker specimen is neither sacrificed nor altered. A number of replicas can be made on the same specimen to permit the replication and study of the whole surface area from the base to the tip of the whisker. Electron micrographs have been taken on replicas of the surfaces of iron whiskers from boats which were prepared by varying the growth conditions. These micrographs show fine details in surface structures which include minute depressions, elevations, and fine parallel grooves and ridges. No interpretation of these structures is made at this time. They will be used in studying growth mechanisms and may facilitate the analysis of the mechanical behavior of iron whiskers at room and elevated temperatures. Author
