... Abstract Cast irons, like steels, are iron-carbon alloys but with higher carbon levels than steels to take advantage of eutectic solidification in the binary iron-carbon system. Like steel, heat treatment of cast iron includes stress relieving, annealing, normalizing, through hardening...

... changes are ignored. Because the system considered so far contains only one pure metal, it is known as a unary system. 1.2 Binary Systems Now consider the addition of a second metal, for example, an alloy of nickel and copper. The phase diagram for this system is shown in Fig. 1.1 . This is known...

... based on eutectic compositions for various reasons, including the minimization of both energy input and coring, or alloy segregation. For example, the iron-carbon system has a eutectic at composition of 4.3 wt% C, which is the basis of cast irons. Many other binary systems have phase diagrams...

... of the precipitation of a phase based on β-manganese. By examining the phase diagram for C-Fe-Mn ( Fig. 14.4 ), as well as the diagram for Al-C-Fe, the researcher determined that the problem could be solved through the addition of carbon to the Al-Fe-Mn system, which would move the composition away from the β...
