Metallurgical Examination of 4 inch-6 inch Thick Cast Armor

Abstract

Cast armor plates were subjected to a metallurgical examination including fracture tests, hardness surveys, macroscopic and microscopic examinations, V-notch Charpy tests, hardenability tests and chemical analysis. In general, crystallinity detected in the sections was due to slack quenching and also to temper embrittlement (too slow cooling from the tempering temperature).
