... This chapter describes the iron-carbon phase diagram, its modification by alloying elements, and the effect of carbon on the chemistry and crystallography of austenite, ferrite, and cementite found in Fe-C alloys and steels. It also lays the groundwork for understanding important metallurgical...

In addition to alloying, there are metallurgical factors, such as crystallography, grain size and shape, grain heterogeneity, second phases, impurity inclusions, and residual stress, that can influence corrosion. Most metals/alloys of technological importance are polycrystalline aggregates...

... for the fcc structure, CN = 12, is the same as that for the hcp structure. A basic rule of crystallography is that if the coordination numbers of two different unit cells are the same, then they will both have the same packing factors. It should also be noted that both the fcc and hcp structures are what...
