Grain structure of metal
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.

WebOct 9, 2003 · Cold working a metal deforms and stresses its crystal structures, causing the metal to work-harden. Steel mills cold-work steel by running it back and forth through rollers with the steel at a temperature below the plastic state. This distorts the steel's grain structure, which increases its hardness and tensile strength while decreasing ductility.
