A program to estimate the kinetics of diffusion-controlled, multiple precipitation reactions in austenitic stainless steels. This program can also be used for the same purpose in different systems for which the SGTE databases provide thermodynamic data, but the user will be required to input the diffusion coefficients.

Language: FORTRAN
Product form: Source Code
Requires: authorisation to run MT-DATA
Operating System: tested on Solaris.

MAP_MT-DATA_KINETICS contains the program which enable the user to obtain an estimate of the volume fraction of various precipitates forming in austenitic stainless steels during ageing at elevated temperature, as a function of time.

All thermodynamic calculations are handled internally by MT-DATA, therefore suppressing the need for the user to input driving forces or equilibrium compositions.

The software uses MT-DATA .mpi files, from which the user selects required phases. This file has to be created in first place, using the ACCESS module of MT-DATA.

Once uncompressed, MAP_MT-DATA_KINETICS contains:
The source code for the program.
A unix shell script to compile the program and link it to MT-DATA object files. It needs to be edited to point to the directory where the latter are found.
A file containing information about a number of precipitates, that is, lattice parameter, number of atoms per unit cell, and parameters for nucleation (nucleation site density and interfacial energy).
spheregrowth.out and planargrowth.out
Contains 500 precalculated points for the solution to the sphere growth and planar growth equations as described in [1].
Complete instructions for installation and use.
