New Exploration of the Nature of Packet Matensite

Abstract

Many controversial data and contradictions about basic feature and behaviour of martensite were exhibited in available investigations. New opinions for following questions, such as the nature and kind of packet martensite, the stereo morphology of lath and plate martensite, the habit plane of martensite etc., have been proposed by the authors through the observation of thirteen steels under optical microscope, scanning electron microscope. It was found that packet M in iron-base alloys can should be divided three kinds: packet thin sheet M, (111) packet plate M and (225) packet plate M
