Controlling GBS involves manipulating the factors that influence it:
1. Grain Size Control: Techniques like severe plastic deformation and nanocrystalline coatings can adjust grain size to optimize properties. 2. Alloying: Adding elements that segregate to grain boundaries can either inhibit or promote GBS, depending on the desired material properties. 3. Thermal Treatments: Controlled heating and cooling cycles can modify grain boundary structures, thereby influencing GBS behavior.
