Abstract : The purpose of this investigation was to make a metallurgical examination of these plates similarly quenched in order to determine the cause of discrepancy in hardness on the rear face of the carburized plate and the same heat of steel in the homogeneous condition. The results of this investigation indicate that: the hardness differential on the face hardened plate is due to pronounced decarburization on the back of the plate. The rear face of the face hardened plate was decarburized to a depth of about 1/4 inch while the homogeneous plate was decarburized to a depth of only 1/32-in- 1/16-in. The grain size of the face hardened plate and the homogeneous plate was practically the same and,
