Intrinsic Defects

Materials science; Metallurgy

An intrinsic defect is formed when an atom is missing from a position that ought to be filled in the crystal, creating a vacancy, or when an atom occupies an interstitial ...

Line Defects

Materials science; Metallurgy

Line defects, or dislocations, are lines along which whole rows of atoms in a solid are arranged anomalously. The resulting irregularity in spacing is most severe along a line ...

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 ...
