A powerful suite of software for modelling of the thermodynamics and kinetics of solid-state transformations in steels. Calculates Widmanstatten, Bainite and Martensite start temperatures.This program is to be used with MTDATA.
Language: | Fortran |
Product form: | Source cord |
Platform: | Linux |
Complete program.
MTTTDATA is a very powerful program for the modelling of transformations in steels. This program enable you to calculate not only TTT diagrams but kinetic and thermodynamic information such as free energy changes accompanying phase transformations. And MTTTDATA is a sophisticated combination of MUCG73(46) and MTDATA thermodynamics database software.
