If the same steel is quenched rather than being cooled slowly, the carbon atoms do not have time to form cementite. They are trapped within a frozen austenite structure in an arrangement called martensite. Movement of dislocations is very difficult in this structure so the metal becomes very hard and brittle.n these circumstances, annealing takes place while the metal is worked rather than being a separate process. The metal can therefore be worked without it becoming work hardened. Hot working is usually carried out with the metal at a temperature of about 0.6 of its melting point.
