Abstract

This paper shows how shear bands which are produced by slip, and are initially of the width of microbands in interstitial free (IF) steel, thicken to the order of 5–7 times the thickness of microbands. The process involves the operation of two shear bands shearing in opposite senses. The importance of this process is that it is capable of increasing the misorientation of the shear band material such that in principle, shear bands can provide nuclei for recrystallization. This reconciles the observation that sometimes shear band nucleation is observed, while in others, it does not happen.
