The interaction of dislocations with grain boundaries is considered a controlling process for many of the mechanical properties, including strength in a metal. The grain boundary acts as a barrier to impede the motion of dislocations, and strengthens the material because of the increased stress necessary to induce slip propagation.TEM samples were prepared from type 304 stainless steel which was solution treated, lightly deformed, electropolished using standard techniques, and examined in a JEOL 200CX TEM operating at 200KeV, using a double-tilt goniometer stage.
