Inhomogeneous material properties such as corrosion resistance, strength and creep can be found in cast or formed metals which are heat treated. The spatial variation comes from the gradient in grain sizes, which is a problem for any industry which forms/bends high strength metals such as in petrochemical refinery.

Coupling between grain growth and grain rotation
Applied Physics Letters, 2007Grain boundary motion during grain growth or recrystallization is considered as a diffusion process of atomic movement across the boundary. It can be accompanied by subgrain rotation or nanograin rotation. However, grain boundary migration can be achieved also by dislocation motion or creep.
