- ‘The yield stress of iron single crystals are very sensitive to both temperature and strain rate and a similar dependence has been found for less pure polycrystalline iron.’
- ‘This polycrystalline silicon is not much use for electronics, since the flaws degrade the conductivity; but it is used, for example, to make silicon solar cells, which are the most common commercial photovoltaic devices.’
- ‘The viscosity that governs the creep of a polycrystalline solid material, such as Earth's iron magnesium silicate mantle, is expected to be a strongly 3D function of position.’
