- Pearlite is a diffusion-dependent eutectoid mixture of ferrite and cementite plates that forms during slow cooling of steel with around 0.76% carbon. It has a tensile strength of around 120,000 psi. - Bainite is a diffusional transformation of austenite to ferrite and cementite that forms as needles or plates depending on temperature. Upper bainite resembles pearlite while lower bainite forms black needle structures. - Martensite is a non-equilibrium body-centered tetragonal structure that forms via a diffusionless transformation from austenite during rapid quenching, trapping carbon atoms interstitially. It is very hard butRead less
