The purpose of this report was to compare the effect of various homogenizing cyces on the macro and microstructure of chromium-molydbenum case armor plate. The results of the microscopic examinaion indicated that the heat treatments which promoted the maximum grain refinement consisted of normalizing at 2100 F for 12 to 16 hours, and renormalizing at 1700 F for 5 hours.
