Recrystallization in Metals

Which metals? Which grades? What's your application?

The classical definition of work in engineering is the amount of energy transferred to a system in determined conditions. Example, a force aplied to a body x the body travel in the direction of the force.

Recrystallization is a phenomen that occurs in metals under determined conditions that alter its microstructure and alloy elements distribution. It depends on the part geometry, thickness, time, temperature, etc.

Please be more specific in your question.

The amount of STRAIN needed for recrystallization depends on the metal and obviously the percentage of cold work applied. The CRITICAL STRAIN ((the amount of strain just needed to initiate recrystalization)) can be anywhere from 0- to 5% elongation in pure tension but is also influenced by annealing temperature . Figures given are for pure Aluminum or Iron (RWK Honeycombe Plastic deformation of metals, ASM, 1984.)

If you draw a very tall sigmoid curve, Temp on y axis, time on x axis, the bottom of tha S is the relaxation area; the next segment denotes recrystallization, and after that grain growth is represented.

This is all specific by metal and obviously your ability to uniformly create strain throughout the section.
