Point Defects

Materials science; Metallurgy

Point defects are where an atom is missing or is in an irregular place in the lattice structure. Point defects include self interstitial atoms, interstitial impurity atoms, ...

Isothermal Annealing

Materials science; Metallurgy

In this process,hypoeutectoid steel is heated above the upper critical temperature and held for some time at this temperature.This is done in order to get a completely austenitic ...

Partial Annealing

Materials science; Metallurgy

Partial annealing is also referred to as interstitial annealing or incomplete annealing.In this process,steel is heated between the lower critical temperature and the upper ...

Recrystallization Annealing

Materials science; Metallurgy

Practically all steels,which have been heavily cold worked,are subjected to this treatment.The process consists of heating steel above the recrystallization temperature and ...

Annealing

Materials science; Metallurgy

Annealing,in general,involves heating to predetermined temperature,holding at this temperature,and finally cooling at a very slow rate.The temperature,to which steel is heated,and ...

Full annealing

Materials science; Metallurgy

The term annealing,until and unless specified,means full annealing.It consists of heating steel to austenitic region,followed by slow cooling.Steel is heated to about 30 to 50 ...

Diffusion Annealing

Materials science; Metallurgy

The process,also known as homogenizing annealing,is employed to remove any structural non uniformity.In diffusion annealing treatment,steel is heated sufficiently above the upper ...
