The Property Model Calculator offers predictive models for material properties based on their chemical composition and temperature. The Property Model Calculator is available to all users who have Thermo-Calc 2015b or newer. Pre-built model libraries are included to set up calculations using properties such as driving force, interfacial energy, and phase transition. As of Thermo-Calc 2019a, martensite and pearlite steel models are also available.
Property models are the engine that drive the Property Model Calculator. They simplify the process of setting up the calculations. They expand the functionality available in Thermo-Calc and make the software easier to use.
Models are Grouped within Libraries in the Software
The models are stored within libraries in the software, a library being a group of similar models, for instance, there is a Steel Model Library and a General Model Library. You can also create custom models and develop your own libraries.
Users can evaluate models simultaneously over a range of compositions and cross plot the results, then conduct an uncertainty analysis and plot the results as either a histogram (as shown below using the phase transition model) or as a probability plot.
The Property Model Calculator includes these calculation types:
Several of the examples have accompanying videos that walk you step-by-step through setting up the calculations and explain what the results mean.
Users who have Thermo-Calc 2017a or newer can develop their own models and seamlessly integrate them into Thermo-Calc using the Property Model Development Framework. This vastly expands what users can do with the software by allowing you to customize the software to meet your modeling needs.
Models are developed using the easy-to-learn programming language Python™, and model development is possible without any additional installation using a simple editor, such as Notepad++. Users can also use a Python Integrated Development Environment (IDE) to access advanced features such as debugging of the property models and autocompletion.
Models are automatically encrypted, for safe and secure file sharing. As of Thermo-Calc 2019a, any custom property models saved in Thermo-Calc can also be accessed using the TC-Python API.
