The annealing practice typically consists of heating the material to a sufficiently high temperature to soften it so that it can safely undergo further processing or be used in application. For example, cold-worked alloys are annealed to soften the worked alloy...

.... For a typical 5 s heat cycle to 950 °C (1760 °F), the decarb depth is calculated to be 0.00197 cm (0.00078 in.). This depth is so shallow that decarburization with induction heat treating has never been a problem. Castings, forgings, cold-drawn stock, and hot-rolled products may all have decarburization unless...

... If an alloy of aluminum containing 4% Cu is heated to 500 °C (940 °F) and held for 1 h, the copper will go into solution in the aluminum. After solution heat treating, the alloy is quenched in cold water to room temperature to keep the copper in solution. The alloy is then artificially aged at 170 °C (340 °F...
