Annealing (metallurgy) - Wikipedia

The temperature range for process annealing ranges from 260 °C (500 °F) to 760 °C (1400 °F), depending on the alloy in question. This process is mainly suited for low-carbon steel. The material is heated up to a temperature just below the lower critical temperature of steel.

Effect of Rolling Temperature on Annealing of aa1050 ...

Commercially pure, dilute aluminium alloys, such as AA1050, dynamically generate sub-grains during cold rolling. If AA1050 is rolled at cryogenic temperatures (liquid nitrogen), this large decrease in temperature minimises the occurrence of dynamic recovery during rolling. The result is that the material has a large amount of stored energy and a high dislocation density, thereby giving it a ...

Aluminium alloy - Wikipedia

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system or by names indicating their main alloying constituents (DIN and ISO).Selecting the right alloy for a given application entails considerations of its tensile strength, density, ductility, formability, workability, weldability, and corrosion resistance, to name a few.

For example, air cooling of Ti-6Al-6V-2Sn from the mill annealing temperature results in a tensile strength lower than that ob-tained by furnace cooling. Regardless of the method used, if distortion is a problem, the cooling rate should be uniform down to 315°C (600°F).
