Possibility of wave control of the formation of twinned austenite in the process of the formation of bainitic ferrite

Abstract

An analysis has been performed of the elastic fields of the basic dislocation loops of carriers of shear deformation on {558} γ planes close to the habit planes of the basic component of the bimodal distribution of fer rite habits in a bainite macroplate. It has been shown that there are extrema of the elastic field that can be asso ciated with the creation of plates of austenite twins in the wave regime. The formation of an additional compo nent of the distribution of the ferrite habits is mainly associated with the regions of twinned austenite.

Crystons: basic ideas and applications

“…For instance, the formation of the basic component of a bainitic ferrite macro-plate is capable of stimulating the formation of twins of initial austenite in the wave mode, while in the emerged austenite, sub-laths of the additional component of bainitic ferrite start to grow [38].…”
