Thermo-Calc Software Celebrate 20th Anniversary

Thermo-Calc Software AB are excited to celebrate our 20th anniversary as a company this year. Founded in 1997, we have grown to become a leading developer of software and databases for computational thermodynamics and kinetics, but our history goes back much further than just 20 years.

In honour of reaching the two decade mark, we’d like to share our interesting history with you. Learn how we transformed from a graduate project in the late 1970s in Stockholm, Sweden, to a leading developer of computational thermodynamics and kinetics and the people who are behind our success in our new 20th anniversary video:

 

As we look toward the future, users can expect our software to broaden toward predicting various mechanical properties, application modules (e.g. steel processing) and more. We will continue to release updates on a two-times-per-year cycle, work to expand our growing collection of thermodynamic and kinetic databases and develop new property databases to meet customer demand.

Thank you to all of our users who have made our first 20 years so successful.

Congratulations to the 2017 NIMS Award Recipients

Thermo-Calc Software send our congratulations to this year’s NIMS Award recipients, Dr. John Ågren, Dr. Bo Sundman and Dr. Kiyohito Ishida. According to the NIMS announcement, the three were selected because they “have advanced the field of computational thermodynamics and developed thermodynamic calculation software.” Both Dr. Ågren and Dr. Sundman are original developers of Thermo-Calc and Dr. Ågren is currently a Senior Scientific Adviser at Thermo-Calc Software.

The NIMS Award has been given out since 2007 and is, “given to researchers with outstanding achievements in the development of scientific technologies for application in various substances and materials.” Scientists are nominated from around the world and winners are selected after a rigorous examination by a panel of scholarly experts.

The three recipients will be celebrated at the 2017 NIMS Week, an academic symposium and business convention held October 4-6 at the Tsukuba International Congress Center in Japan.

Congratulations to all three recipients on this prestigious award.

 

Thermo-Calc Presentation Highlighted at EUROMAT 2017

Join Thermo-Calc Software at the premier conference on materials science in Europe, EUROMAT 2017, where we will be giving three presentations, one of which has been selected as a highlighted presentation. Additionally, John Ågren, who recently joined the company as a scientific adviser, will be giving a plenary talk at the conference, Computational modeling and Materials Design.

Thermo-Calc 2017b Release Preview

Thermo-Calc 2017b is scheduled for release late fall 2017. The release includes many exciting upgrades and new features, such as:

New and Updated Databases:
Thermo-Calc 2017b includes several new databases. TCNOBL1 is a noble metal alloys database being offered for the first time this release.

We will also be offering two new titanium databases. TCTI1 is a brand new Titanium database, covering both Ti and TiAl alloys, and has been developed by TCS AB in collaboration with a project with industrial partners. MOBTI2 is the second edition of the titanium mobility database and will be compatible with TCTI1.

The 2017b release includes updates to two other databases: the aluminium database TCAL5 and the general alloys database and SSUB6, as well as an upgrade to TCHEA2.1.

New Features in the Diffusion Module (DICTRA): The graphical mode version of DICTRA, known as the Diffusion module, includes several new features that extend the functionality and flexibility of the program and make it more user friendly.

  • It will be possible to set boundary conditions.
  • A new advanced mode gives users more control over the plots and allows you to plot additional combinations, such as the composition at a specific time. You can now also plot user-defined functions, giving you a lot of flexibility in the plotting.
  • All regions are now visible in the Configuration window. Small regions that would be too small to see are now represented with a dashed line, as shown in the image below.
  • A tool tip appears when you hover over a region which shows the name of the region, the width of the region and the number of grid points, as shown below.

    In the Diffusion module (DICTRA) small regions which were previously not shown are now visible with a dashed line. Additionally, a tool tip appears when you hover over a region which shows the name of the region, the width of the region and the number of grid points.

  • Composition profiles are now visualised before you plot the results. A useful tool tip explains how each one works and how to set them, as shown below.
  • User defined functions (using Python) can be added in the new composition profiles feature, allowing you to see if there are any mistakes before you plot the results.

    Composition profiles are now visualised before you plot the results and a tool tip helps users set the composition profile.

New Features in the Precipitation module (TC-PRISMA): The Precipitation module (TC-PRISMA) has received several new features, the biggest upgrades are:

  • Elastic strain energy effect on precipitation can now be taken into account. Default values will be offered for each type of alloy or users can provide their own data. An elastically homogeneous system is assumed.
  • Non-spherical morphology of precipitate particles can be treated. If desired, the evolution of the shape factors for cuboids, plates or needles can be predicted together with the size.
  • A bug that sometimes led to a sudden stop of a simulation because of the “negative matrix composition” error has been fixed.

3D Plotting: Thermo-Calc 2017b includes 3D plotting for Grid calculations in the Property Model Calculator and the Equilibrium calculator.

Improvements to the Scheil calculator: The Scheil calculator has improved auto scaling which removed a bug that showed negative phase fractions when simulations were plotted. The calculator has several other bug fixes.

Usability Improvements and Bug Fixes

  • Users can now enter custom contour values in contour plots.

    Users can now add their own custom contour values to contour plots. The program auto-adjusts the scaling on the plot to show the custom values.

  • Using the tab key to jump to a text box now auto-selects all text in the box.
  • The periodic table has higher contrast colours for selected/deselected elements.
  • A bug was fixed that caused the graphical mode of Thermo-Calc to scale oddly on high resolution screens.
  • Many other bug fixes

 

Thermo-Calc Software Welcomes John Ågren to the Company

John Ågren

Thermo-Calc Software are excited to announce that Prof. John Ågren has joined the company as a Senior Scientific Advisor.

Prof. Ågren was one of the original developers of Thermo-Calc in the late 1970s, working with two others, Bo Sundman and Bo Jansson, to write the preliminary code and develop the initial databases as part of their doctoral thesis projects at the Royal Institute of Technology (KTH) in Stockholm, Sweden. The three students were working on separate projects, but each needed access to thermodynamic data, so they set out to create collaborative software to help them complete their research, and by 1981, they had completed the first version of Thermo-Calc. The software was soon licensed to other organisations, and in 1997, the company Thermo-Calc Software AB was founded. Continue reading
