Cold worked aluminum alloys acquire strain hardness, requiring the material to be annealed. The recrystallization temperature of alloys may vary from 340 to 400°C (650 to 750°F) the temperature and the rate of heating is specific to the alloy and must be carefully applied. The recrystallization temperature for cop- per usually ranges from 200°C to 400°C.Highly purified copper will recrystallize at 100°C if annealed for a long time. Abstract. The thermal treatment of cold rolled aluminum 1060 produced by the continuous casting method has been found to produce defective cups lacking in height during cupping. The annealing process involves heating to 480°C for 6 h and stepping down to 420°C for 2 h, to evolve a microstructure with good mechanical properties that will enhance material formability. Iron and silicon are the inevitable impurities in commercial purity aluminium alloys.

When the solution is later cooled, after filtering out insoluble impurities, the amount of solute that remains dissolved drops precipitously.

Transmission electron microscopy confirms that the dislocation densityis increased and subgrain size is decreased with an increase in strain rate and decrease of the test temperature. 2009-02-06 · 580 C is enough temperature.

In this stage, the recrystallised grains grow […] The key features necessary for a successful recrystallization process, are a very controlled temperature decrease and sufficient time. Because most solids have a better solubility at higher temperatures, we can sat- urate or almost saturate a solution at high temperature (usually the boiling temperature of the solvent), and then slowly allow the solution to reach room temperature. A method of treating metal stock to lower the recrystallization temperature thereof comprising casting the metal into a continuous bar in a moving mold formed by a groove in the periphery of a casting wheel and an endless belt lying adjacent the groove along a portion of the periphery of the wheel, hot-working the bar substantially immediately after casting while the bar is in substantially Recrystallisation temperature explained for HSC Engineering Studies.For the concepts of cold work, please see the work hardening videos in this series.Recove 1.

The influence of alloying additions upon the annealing behaviour of aluminium after cold working and during hot working was studied. It is shown that alloying additions, such as magnesium or zinc, that are present in solid solution in the aluminium throughout processing, result in a reduction in the static recrystallization temperature after cold working and can result in dynamic and silicon on the recrystallization texture of drawn aluminium.

The thermal treatment of cold rolled aluminum 1060 produced by the continuous casting method has been found to produce defective cups lacking in height during cupping. The annealing process involves heating to 480°C for 6 h and stepping down to 420°C for 2 h, to evolve a microstructure with good mechanical properties that will enhance material formability. Iron and silicon are the inevitable impurities in commercial purity aluminium alloys. The precipitation reaction due to these impurities easily occurs during heat treatment at the temperature range of 200 – 600 o C, affecting cold working, softening, and corrosion resistance of the alloys. Effect of annealing temperature on the recrystallization texture of 95% cold- rolled, Al-0.007%Fe alloy; (a) As rolled, annealed at: (b) 280 C, (c) 360 C, (d) 520 C, (Lu¨cke 1984). The grain size of Alloy A (about 20–30µm) was found to be smaller than that of Alloy B. Hardness of Alloy B decreased significantly in the temperature range from 473 to 573 K due to the recrystallization during the annealing.
