Austenitic Stainless Steel 304

Though there developed same concentrations of special grain boundaries (SBs) in grain boundary engineered (GBE) austenitic stainless steel (304 stainless steel) and a Pb-Ca based alloy, the makeup of SBs, size distribution of clusters of grains with ∑3n (n=1,2,3) orientation relationships (∑3n CG), and grain orientations (textures) are quite different between the two specimens, suggesting there have two different mechanisms separately governing the evolution of grain boundary character distributions (GBCDs) in the two types of materials during GBE processing.
