Grain chemistry

Webgrain, in metallurgy, any of the crystallites (small crystals or grains) of varying, randomly distributed, small sizes that compose a solid metal. Randomly oriented, the grains contact each other at surfaces called grain boundaries. The structure and size of the grains determine important physical properties of the solid metal. WebSep 25, 1997 · The motion of 〈101̄0〉/θ ice grain boundaries is studied using the “Sun−Bauer” technique. The samples were annealed at temperatures between −2 °C and −20 °C, for times up to 1400 h, and Mγ values for mixed and tilt boundaries were determined (M and γ are the mobility and the excess of free energy per unit area of the grain …
