To prevent grain boundary sliding so that creep is less likely to occur, usually engineers would design components of larger grains or have columnar grain structure to prevent grain-boundary sliding. Why this two method can prevent grain-boundary sliding? For columnar grains, would they be more easy to slide against each other since the grains are parallel?

I would like to know why grain boundary sliding can be prevented by columnar grain arrangement? what does it related to the mechanism of creep?
