Grain boundary maps

In materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are two-dimensional defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. Most grain boundaries are preferred sites for the onset of corrosion and for the precipitation of new phases from the solid. They are also important to many of the mechanisms of creep. On the other hand, grain boundaries dis… WebDeformation mechanisms are commonly characterized as brittle, ductile, and brittle-ductile.The driving mechanism responsible is an interplay between internal (e.g. …
