Grain boundary sliding in creep

    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?
