Definitions for "Cold working"
Changing the structure and shape of steel by applying stress at low temperature.
Changes in the structure and shape of steel achieved through rolling, hammering, or stretching the steel at a low temperature (often room temperature). To create a permanent increase in the hardness and strength of the steel. The application of forces to the steel causes changes in the composition that enhance certain properties. In order for these improvements to be sustained, the temperature must be below a certain range because the structural changes are eliminated by higher temperatures.
Material reduction or deformation carried out at temperatures below those resulting in the recrystallization or annealing of the metal. Cold working of the metal will bring about strain-hardening with an increase in strength and hardness.
The general name for sandblasting, grinding and polishing the glass. While many artists use the procedures of cold working as part of their artistic creation, most would prefer to avoid the labor intensive process of grinding off punty marks and polishing the result.
Any work, grinding, surfacing, and drilling that is done on the glass that has been finished after the annealing process is completed. Working without heat.
Distortion of the grains in the vicinity of a gouge. Cold working often occurs immediately under the visible gouge and can significantly reduce the mechanical properties of a pipe steel.
The collective term for the many techniques (such as copper-wheel engraving) used to alter or decorate glass when it is cold.
