Study of Ballistic Protective, Chemical and Physical Properties of 200 M-1 Helmets and 200 Helmet Blanks

Abstract

A study of M-1 helmets was conducted to find an inspection technique to replace the V(sub P) 50 as a quality control index of ballistics performed. the V(sub P) 50 of 200 helmets and 200 helmet blanks representing 200 heats of steel was determined. Other parameters studied were thickness, hardness, chemical composition, microstructure, and tensile stress-strain properties. Of these, only thickness was found to be sufficiently sensitive of V(sub P) 50 to be of value as a quality control cirterion. Recommendations are made for a study leading to the implementation of these findings. Among other observations made in the study was the possibility that significant improvement in ballistic resistance of M-1 helmets might result from annealing the helmets after forming. Recommendations along this line are also made.
