Grain boundaries., Electrons--Backscattering., Twinning (Crystallography)


Grain boundary engineering can be used to improve the properties of a material by manipulating the grain boundary character via thermomechanical processing. Several studies have shown that properties such as corrosion resistance, creep resistance, and fatigue crack propagation resistance can be improved as the percent of special grain boundaries (3<Σ
