Is there any extensive literature, dataset or open source/free software for generating CCT and TTT diagrams for steels
I am not aware of any open source or free software, but one of my colleagues (Pieter van der Wolk) did his PhD at Delft University on this topic. His thesis entitled "Modelling CCT-Diagrams for Engineering Steels under Neural Networks"can be dowloaded from the University library:

From what I can remember, the demo version of ThermoCalc only allows two component systems. You could also use JMatPro, MatCalc etc. but these are also not free.
You can find a software from researchers in the phase transformation group at the University of Cambridge, the program is called mucg.
e.g. http://www.msm.cam.ac.uk/map/steel/programs/mucg83.html
You can generate CCT & TTT diagrams at this site, which I believe uses the program mentioned by Mathew, the Materials Algorithms Project Program Library

Thermocalc and matcalc can calculate TTT for precipitation reactions but I'm not aware that they can model phase transformation from austenite to ferritic daughter products.This is something jmatpro can do.
U can try with JMatPro, can help with calculation Ms temperature and TTT diagrams.
This is a good place to start with

Hello
I think this will do for some time:
http://www.steeldata.info/
It seems the http://calculations.ewi.org/vjp/secure/TTTCCTPlots.asp site has been taken down recently (as of July 14, 2017). Does anyone know if this has been just moved or has it been discontinued?
The site in reference is down for at least 1 month. No answer about why
An excellent online industry-based resource is that from Ovako.
https://steelnavigator.ovako.com/steel-navigator/heat-treatment/calculate
Online software has been developed by:
www.ovako.com
I believe that combining the excellent previous scientifc work of Kirkaldy reported by JMatPro might allow most of us to build his/her own software for quite "general" steels.
Many years ago ( I believe 2008) we built "3d mensionnal" curves of TTT/CCT curves, they were good looking but seems no-one have been using seriously them to date for practical issues..
So a more recenta nd serious option is: Article Modelling of austenite transformation along arbitrary cooling paths
or directly here (for researchgate users):
Article Modelling of austenite transformation along arbitrary cooling paths
Dear Rajeev,
I think you can try with JmatPro.
Software programme JMatPro can be used to develop a model that can provide accurate TTT and CCT diagrams for general steels, including medium to high alloy types, tool steels, 13%Cr steels etc. JMatPro also incorporated a capability to calculate transformations involving ferrite, pearlite and bainite in HSLA steels closely based on the model of Kirkaldy.
Hope it is much helpful to you.
