Thermo-Calc 2018b is released in June 2018 and includes the addition of three key features to the TC-Python API and two new thermodynamic databases for metal oxide solutions and Mg-based alloys.
Read the Thermo-Calc 2018b Release Notes.
TC-Python is a PythonTM-based SDK that enables users to openly couple Thermo-Calc calculations with other software. The SDK is built in the popular Python™ language to give Thermo-Calc users access to many other programs, such as numerical packages like NumPy and SciPy, which can be used in combination with our calculations. It is truly a tool for Integrated Computational Materials Engineering (ICME). Thermo-Calc 2018b adds three important features to the TC-Python API: Scheil calculations, phase diagrams and property diagrams.
Several new examples for each feature are included. You can use these to both learn about the use of TC-Python and as a way to build your own calculation simulations. Additional functionality, such as diffusion calculations, will continue to be added in future releases.
All users with a current Maintenance and Support Subscription, e.g. those who have Thermo-Calc 2018a and newer, are being offered a free trial license of TC-Python until the end of 2018 so you can test the program and discover how you can integrate it into your overall workflow.

A new version of the TCS Metal Oxide Solutions Database (TCOX8) includes the addition of six new elements: Co, Mo, P, V, W, +Ar (only in gas) making it available in a 24-element framework. The addition of the new elements increases the number of assessed systems to 241 binary, 218 ternary, and 104 quaternary systems.
The new version of the TCS Mg-based Alloys Database (TCMG5) has seven additional elements (Dy, Er, Ga, Ho, In, Sb and Sm). In this 31-element framework there are now 195 binary and 91 ternary systems, which includes 92% Mg-containing and 41% RE-containing systems.
The updates to the TCS Al-based Alloy Database (TCAL5) includes an improved description of Al7Cu2Fe, an improved volume description, and Al6(Cu, Fe, Mn) remodelled in Al-Cu-Fe-Mn.
Improvements and Bug Fixes
For Thermo-Calc and the add-on Diffusion module (DICTRA) and Precipitation module (TC-PRISMA), a variety of bug fixes and improvements were done, including to the Quick Start Wizard and an improved interfacial energy function. For details read the Thermo-Calc 2018b Release Notes.
Thermo-Calc 2018a was released in March 2018 and includes an entirely new API, new databases for aluminium and high entropy alloys, major updates to the Precipitation module (TC-PRISMA).
Highlights of the Thermo-Calc 2018a release:
Thermo-Calc 2018a includes a new PythonTM API called TC-Python. This new API allows users to couple Thermo-Calc calculations with other software in an open way, making it an integral part of the ICME framework.
The API was built in PythonTM because it is a popular language which gives users access to many other programs, such as numerical packages like NumPy and SciPy, which can now be used in combination with our calculations.
In this release, TC-Python focuses on equilibrium calculations and the Precipitation module (TC-PRISMA), making it the first Thermo-Calc API that allows users to make precipitation calculations. Users who do not have a Precipitation module (TC-PRISMA) license can still make calculations with up to three elements using the DEMO license for the Precipitation module included in your software.
We will continue to expand TC-Python and plan to offer step, map and Scheil calculations, as well as Diffusion calculations in the coming releases.
All users with a current Maintenance and Support Subscription, e.g. those who have Thermo-Calc 2018a, are being offered a free trial license of TC-Python until the end of 2018 so you can test the program and discover how you can integrate it into your overall workflow.

The 2018a release includes new thermodynamic and kinetic databases for high entropy alloys.
TCHEA3: Six new elements have been added to the thermodynamic high entropy alloys database, bringing it to a 26 element framework (Al, B, C, Co, Cr, Cu, Fe, Hf, Ir, Mn, Mo, N, Nb, Ni, Re, Rh, Ru, Si, Sn, Ta, Ti, V, W, Y, Zn and Zr). This new database also includes more than 100 new binary systems and more than 150 new phases.
MOBHEA1: This is the first kinetic database for high-entropy alloys (HEA) from Thermo-Calc Software. The database is suitable for simulation of diffusion controlled phenomena using the add-on Diffusion Module (DICTRA) and/or the Precipitation Module (TC-PRISMA) and is intended for use with TCHEA3. It can also be used together with all Thermo-Calc programming interfaces. The database consists of 22 elements and 5 phases.
MOBAL4: This new version of our aluminium mobility database adds the element erbium (Er), bringing it to a 35 element framework. The database includes an improved description of liquid and has many new and updated binaries. It also now includes ternary and quaternary descriptions. The database comprises 3 phases, 37 binary systems, 20 ternary systems and 2 quaternary systems.
This release offers improved convergence for phases with charged species. This improvement makes it easier to do equilibrium step and map calculations for oxides.
Updates to the Precipitation module (TC-PRISMA)
There are two major updates to the Precipitation module (TC-PRISMA) in the 2018a release, as well as several smaller improvements.
Updates to the Diffusion module (DICTRA)
The Diffusion module has two new features, one in the Console Mode and one in the Graphical Mode.
Improvements to Usibility
Thermo-Calc 2018a provides several improvements to usability, including:
