    Figure 44 Optical micrograph of a mixed microstructure of bainite and martensite in a medium carbon steel. The bainite etched dark because it is a mixture of ferrite and cementite, and the b interfaces are easily attacked by the nital etchant used. The residual phase is untempered martensite which etches lighter because of the absence

    Austenite and ferrite. Austenite was originally used to describe an ironcarbon alloy, in which the iron was in the facecentredcubic gammairon form. It is now a term used for all iron alloys with a basis of gammairon. Austenite in ironcarbon alloys is generally only evident above 723C, and below 1500C, depending on carbon content.

    So, here due to etching, microstructure divides into two phases. White phase is Cementite and black phase depicts pearlite. Cementite is Iron carbide extremely resistant against etchants, thats why no chemical reaction happens on this phase. Matrix of pearlite appears to be black here. Pearlite consists of ferrite and cementite.

    Secondly, cementite will appear and the austenite that remains in between the plates will transform to a mixture of ferrite and cementite. Ferrite is thus regarded as the leading phase. In this chapter, the term bainite will always mean an acicular microstructure composed of ferrite and cementite.

    The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.

    Cementite forms directly from the melt in the case of white cast iron. In carbon steel, cementite precipitates from austenite as austenite transforms to ferrite on slow cooling, or from martensite during tempering. An intimate mixture with ferrite, the other product of austenite, forms a lamellar structure called pearlite.
