ABSTRACT:
Method of nondestructively measuring percent elongation or ductility of a cellular metallic. After surface preparation, the number of metal cells per unit area are counted, either manually or using an automated technique. The cell count is utilized in a relationship unique to the cellular metallic which correlates cell count to ductility in terms of percent elongation. The effects of the structural configuration of the cellular metallic, porosity and eutectic morphology are also discussed.
