The program is used to calculate the equilibrium transformation temperatures of steel. The highest temperature at which alpha-ferrite starts to form from austenite is Ae3 and taht at which austenite completely transforms to ferrite is Ae1.
creep_ae.mpiContains the inputs for MTDATA
creep_ae.mprResult from MTDATA calculations
comp_dataContains composition in the order specified in Readme.txt file
equil_tempContains the transformation temperatures
EQILIBRIUM_temConsists of percentage of phases at each temperature of calculation. This can be used for checking if the transformation temperatures make sense.

Follow the steps listed below to use the module :
