Abstract

A computer program for the Boltzmann-Matano solution to Fick's second law in semi­infinite binary diffusion couples is presented. The program is written in FORTRAN for the IBM 7090 digital computer. An error function curve fit is used to interpolate between and smooth experimental data, and the calculations performed on the regenerated data.
Examples are given of application of the program to incremental couples with no inter­mediate phases and to pure metal couples with and without intermediate phases. Phase boundaries in couples with intermediate phases can also be obtained with a high degree of accuracy. By substituting lattice spacings for ordinary distance units, a correction for molal volume change due to composition differences can be programmed.
