Abstract
An algorithm and programs are developed for optimizing the experimental study of isobaric–isothermal phase diagrams of quaternary systems with constant-composition phases or phases with narrow homogeneity range. These include (a) a program for enumerating phase diagrams with phases of specified composition and (b) an algorithm and a program software for the iterative analysis of phase diagrams. At each iteration, the researcher enters experimental data into the program to obtain a list of compositions for further study. Data are presented from modeling the plotting of phase diagrams with one binary, three ternary, and one quaternary compounds. It is found that among ten given examples, the number of iterations sufficient for charting the diagram is 1 (one example), 2 (four examples), 3 (two examples), 4 (one example), and 5 (two examples).
