ACCURATE ORIENTATION RELATIONSHIPS BETWEEN FERRITE AND CEMENTITE IN PEARLITE

摘要

In most previous work [1-5], thg interlamellar interface between pearlitic.territe and cementite is considered to have a low energy and dislocations have jbeen observed at the interfacial boundary, in botli plain carbon steels [2] and high manganese steels [3,4]. This implies that an orientation relationr ship (OR) exists between pearlitic ferrite and cementite. Over the past decades, there have been a number of experimental determinations of the OR in pearlite [6-11], but only three have been consis tently reported in the literature.
