MT-DATA is not currently installed on the computers in the M.Phil. room 210. We will therefore access the software via remote computers. The Demonstrator will log you in and start MT-DATA.
With a nice web browser such as FireFox, open instructions.
Follow the examples given in Getting started; on the web page. Then try to do the following:
simple equilibrium calculation for Fe, 1.0 Mn, 0.1 C (wt%), leaving only BCC_A2, FCC_A1, liQUID and CEMENTITE (at 573K).
With the same system and phases, do a stepped calculation between 673K and 1673 K, for two different Mn levels (1.0 and 6.0 wt%). Each time, plot the amount of phases as a function of temperature. Compare.
Calculation of the driving force for the formation of cementite from ferrite (BCC_A2) at 573 K for Fe, 1.0Mn, 0.1C wt%. For this, you will need to find, in the output of a single calculation (e.g: compute print brief print mole !) the gibbs free energy of your system.
If you have some more time, try more advanced examples from the web page, such as 'calculating an isopleth' (in APPliCATIONS).
