Solution The illustration below is the Cu-Zn phase diagram (Figure 9.19). A vertical line at a composition of 68 wt% Zn-32 wt% Cu has been drawn, and, in addition, horizontal arrows at the four temperatures called for in the problem statement (i.e., 1000 °C, 760 °C, 600 °C, and 400 °C). Excerpts from this work may be reproduced by instructors for distribution on a not-for-profit basis for testing or instructional purposes only to students enrolled in courses for which the textbook has ...
Please suggest me how I can calculate Weight fractions of mixed phases and how to plot pseudo phase diagram (T vs mol%). Thanks in advance . NaYF4.jpg.

For phase 1 , it is equal to b/(a + b). However, algebraically, the expression is still to some extent awkward; the fraction of phase 1 in Fig. 2 is equal to: (5) 1 = (C T − C P) 2 + (B T − B P) 2 (C 1 − C P) 2 + (B 1 − B P) 2 1 / 2 in which T and P refer to the total composition and the one on the tie line between phases 2 and 3 in Fig. 2.
Weight fraction phase diagram. Fraction of a phase is determined by taking the length of the tie line to the phase boundary for the other phase, and dividing by the total length of tie line The lever rule is a mechanical analogy to the mass balance calculation. The tie line in the two-phase region is analogous to a lever balanced on a fulcrum. Wα.
