…Normal steel is a two-phase alloy of ferrite and cementite. In addition, alloys with compositions that exhibit characteristic solidification, phase transformations, and reactions such as eutectic, constant-melting-point solidification, and eutectoid reactions are called eutectic alloys, constant-melting-point alloys, and eutectoid alloys, respectively. As mentioned above, alloys are classified by the main component elements, such as zinc alloys and titanium alloys, but they can also be classified by characteristics and uses, as shown below. … *Some of the terminology that refers to "eutectoid alloys" is listed below.
