EFFECTS OF ALLOY SEGREGATION ON SPALLING OF METALLIC ARMOR MATERIALS,

Abstract

Several illustrations of the spall crack propagation in cast and wrought metallic armor alloys have been presented. Dendritic or banded structures resulting from alloy segregation during solidification of the metals have been shown to be related to spall crack propagation. Neither working nor short-time homogenization treatments significantly effect the alloy segregation. Hence, minimization of the banding (alloy segregation) appears to be dependent on a better understanding of, as well as control of, the solidification process. (Author)
