The properties of steels are controlled by the carbon content, the alloy content, and the thermal treatment. When a steel is cooled faster from the gamma (austenite region) below the eutectoid temperature, the lamellar, alternating platelets of ferrite and carbide in pearlite get thinner and are more closely spaced. Why do you think that this is so? What do you think will happen to the strength and ductility of the steel which has been cooled faster and why do you think that is so?
