Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Recrystallization behavior during optimized heat treatments provides a potential to obtain
desirable grain structure, which significantly improves the mechanical properties of …

Grain rotation is a well-known phenomenon during high (homologous) temperature
