Nabarro-Herring creep
= Nabarro-Herring creep
{c}
Diffusional <material creep> dominated by transport through grain interiors. For an equiaxed-grain model, $\dot\varepsilon\sim C D_V\Omega\sigma/(k_BT d^2)$, with geometric factor $C$, atomic <volume> $\Omega$ and <grain size> $d$. It is linear in <stress> in this ideal limit.
