Heat treatment of steel | Annealing | Normalizing | Recrystallisation | Soft annealing | etc.

In this video we look at the heat treatment of steels, in particular the annealing that can be used to control the properties of steels. This includes normalising to achieve a homogeneous microstructure. Soft annealing to achieve good formability and machinability. Coarse grain annealing to improve machinability in low carbon steels. Diffusion or solution annealing to homogenise alloying elements or dissolve precipitates. Recrystallisation annealing to restore an undeformed microstructure. Stress-relief annealing to reduce residual stresses. Hardening and tempering as a heat treatment to increase strength or hardness is also generally considered a heat treatment process, but not specifically an annealing process. 00:00 Annealing process 00:54 Normalizing (annealing) 03:51 Soft annealing 07:18 Coarse-grain annealing 08:45 Recrystallization annealing 12:03 Diffusion annealing 13:40 Solution annealing 15:11 Stress relief annealing 16:55 Summary 17:57 Quenching and tempering
