MTDATA script – driving force

Here is a quick example script to calculate driving force for formation of ferrite from austenite.


mu
define system 'Fe,Cr,Ni,Mo,N,C,Mn' source tcfe !
% fe Cr Ni Mo N
set w(1) undef w(2) 23.00 w(3) 9.0 w(4) 3.0 w(5) 0.15 !
% C Mn
set w(6) 0.02 w(7) 0.8 !
set w 100 !
classify absent p(*) !
step temp 973 1273 10 !
%
% calculating for FCC
%
classify normal p(FCC_A1) !
compute print brief print mol !
compute print graphics_output !
units temperature celsius !
ordinate gibbs system !
plot tabulate spreadsheet !
%
% calculating for BCC
%
classify normal p(BCC_A2) !
compute print brief print mol !
compute print graphics_output !
units temperature celsius !
ordinate gibbs system !
plot tabulate spreadsheet !


This gives the answer in Joules / 100 kg.
