1.1 Components
Total of 19 components are included in the database as listed here:
Major alloy elements: Cu, Cr, Fe, Mn, Ni, Pb, Si, Sn, Zn
Minor alloy elements: Al, B, Bi, C, P, S, Sb, Se, Ti, and Zr
1.2 Suggested Composition Range
The suggested composition range for each element is listed in Table 1.1. It
should be noted that this given composition range is rather conservative. It is
derived from the chemistries of the multicomponent commercial alloys that
have been used to validate the current database. In the subsystems, many of
these elements can be applied to a much wider composition range. In fact,
some subsystems are valid in the entire composition range as given in Section
1.4.
