A REPLICATION TECHNIQUE FOR THE STUDY OF A BRITTLE FRACTURE OF SHIP PLATE STEEL BY ELECTRON MICROSCOPY

This investigation was undertaken to study the applicability of electron microscopy in determining the relationship of microstructure of ship plate steel to its brittle fracture transition temperature in order to obtain a broader understanding of the phenomena involved in the brittle failure of plating in ship hulls under service conditions. The results for a series of specimens of differing transition temperatures indicate that there is a relationship between the degree of separation of cementite lamellae and the temperature in the transition from predominantly ductile to predominantly brittle fracture: An increase in cementite ordering is correlated to higher transition temperatures.
