ABSTRACT
Dislocation arrays near two grain boundaries in type 304 stainless steel have been studied using transmission electron microscopy (TEM) and anisotropic elasticity. The slip propagates by different mechanisms across these boundaries. One configuration was analyzed elastically, and the local stress field and forces claculated. The combination of these two techniques allows estimation of the lattice friction stress on dislocation glide. A value of ~12MPa was obtained in this study.
