FORTRAN program to calculate the mole fraction of precipitates and wt% of solute in ferrite. It also calculates the effective diffusivity which is proportional to the interface velocity of a precipitate considering a multicomponent system. The program should not be used for systems which contain more than one precipitate phase. This program uses MTDATA.
Language: | FORTRAN |
Product form: | Source Code |
Platform : | Sun OS |
Complete program.
The files associated with this module are :
creep_module.mpi | Contains the inputs for MTDATA. |
creep_module.mpr | Result from MTDATA calculations. |
comp_data | Contains composition in the order specified in Readme.txt file. |
temp_only | You need to specify the temperature values in this file for the corresponding composition in the file "comp_data". The temperature at which phase stability calculation is to be performed will be read from this file. |
MTDATA_OUTPUT | All the calculations done by MTDATA are printed in this file. |
ppt_fraction_c | Contains mole fractions of all the phases. |
SOLID_SOLN | This file contains information about the wt% of dissolved solutes in ferrite. The format of this file is Cr Mo W V Nb N C (all in wt%). Note this format, since the file itself will not have any information about the format. |
Deff.dat | Contains the effective diffusivity (Deff) of M23C6, M6C, Laves Phases, HCP_A3, M7C3, VN, NbC and NbN respectively. The format of the file follows the same order. |
one_by_D_eff.dat | This file contains information about 1/Deff. Format of the file is same as in "Deff.dat". The values in this file can be approximated to the interface velocity of a precipititate considering multicomponents NOT multiphase. Calculated as in reference 1. |
