Early Stage of Deformation in a Bainitic Steel

Abstract

Tensile deformation behavior at an early stage in a bainitic steel has been examined by detecting formation of surface relief, and analyzed stereographically. The variants of bainite could be identified by both morphology and crystallography. The surface relief was detected in a bainite-variant at an early stage of deformation. It could be analyzed that the variant with surface relief has many slip systems of larger Schmid factors compared with those that other variants have, resulting in the early stage of deformation of bainite being largely dependent on Schmid factor.
