= Coble creep
{c}

Diffusional <material creep> dominated by grain-boundary transport. An ideal scaling is $\dot\varepsilon\sim C\delta D_{GB}\Omega\sigma/(k_BT d^3)$. Its stronger grain-size dependence and typically lower transport <activation energy> distinguish it from bulk-diffusion <material creep>.
