annealing
Annealing, in metallurgy and materials science, is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for a suitable amount of time, and then cooling.
In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating, and cooling rate. Hot working or cold working after the annealing process alter the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to adjust between harder and more brittle, to softer and more ductile.
In the cases of copper, steel, silver, and brass, this process is performed by heating the material (generally until glowing) for a while and then slowly letting it cool to room temperature in still air. Copper, silver and brass can be cooled slowly in air, or quickly by quenching in water, unlike ferrous metals, such as steel, which must be cooled slowly to anneal. In this fashion, the metal is softened and prepared for further work—such as shaping, stamping, or forming.
Selling my annealeez brass annealing machine. Retails for $275, looking for $175. Has regular and magnum wheels. Comes with the tray. Make me an offer!
It is fairly amazing how much controversy arises with respect to cartridge annealing. Shooters are all over the map. Some anneal after every firing. Some never anneal. Some say annealing brings greater accuracy, others say that its impact on accuracy is negligible at best. The conflicting...
I am selling my Bench Source Annealer that I have only used twice. It is a great machine and will do a lot of brass very quickly, but I ended up getting a different setup that I can automate with the stuff I have already. I am throwing in a nearly full bottle of 650 degree tempilaq and two hoses...
Hi,
Selling my Giraud Annealer very low mileage 308 and 300 win mag discs (and whatever other cartridges those discs hold).
Couple tanks of gas. Easy to use, get it set and stack a bunch of cartridges into it and let it run. Couple partial bottles of Tempilaq paint for checking temperatures...
