摘要: Atomic force microscope (AFM) examination was performed on plain carbon steels. A 1018 steel that austenized and furnace cooled revealed raised grain boundaries when etched with nital. It concluded these consist of walls cementite formed during cooling below the eutectoid temperature. Examination using AFM done 1045 1095 steels had been water quenched after austenizing. Lath martensite also platelets were less than bainite These structures seen more clearly optical microscopy.
