How does the annealing process affect the hardness of materials? - annealing time calculator
We have annealed 6 samples of commercially pure copper (at 800 degrees Celsius for one hour, then rolled to reductions of 50% in thickness). Each of these persons was subjected to different amounts of annealing after cold rolling.
I will look the problem in the theory and explain how recrystallization annealing, after cold rolling affected the hardness of a sample.
Help please.

Annealing Time Calculator How Does The Annealing Process Affect The Hardness Of Materials?
4 comments:
Treatment of a metal or alloy improved by heating to a predetermined temperature, holding for a certain time, then cooled to room temperature ductility and brittleness. Annealing process is intermittently during the work on restoring a piece of metal ductility lost through repeated hammering or other. Full annealing is done to enable the sustainability of these areas as forged blanks destined for use in industrial machine tools. Annealing is also done to relieve the tension. Annealing temperatures vary with the metals and alloys, and with the desired properties, but must be in an area that prevents the growth of crystals.
Hope this helps

* Full Annealing: (650 - 1650 ° F):
Annealing of ferrous and nonferrous metals, smooth, stress-free structure of the inability of the Mach improved profitability cold, mechanical or electrical properties and dimensional stability. To obtain non-ferrous materials, heat, high temperature above the fundamental transition and maintain the full austenitizing and slowly cooled to room temperature. For non-ferrous alloys heat of the annealing temperature is determined to continue for some time, and the oven cool environment.
Solution: (900 - 2250 ° F):
Annealing process for ferrous and nonferrous metals for the manufacture of a solid solution of alloying elements on hardening or precipitation hardening or improve the processing, design and / or corrosion resistance. This process involves heating at a certain temperature, holding for a fixed term and rapid cooling to room temperature. This process is often tempered as a precursor to an operation of the precipitation - alloy.
Intermediate ANneal F: (500 - 1400 °)
Annealing performed at a temperature below the critical iron weaker material and below the annealing temperature of complete non-ferrous materials. Also known as "annealing process. Annealing is used for the ductility of the material more cold working or hot work.
