Thermo-Calc 2018b released with new TC-Python features

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 (TCOX8) and Mg-based alloys (TCMG5).

Presentation on High Entropy Alloys Database Development

High entropy alloys (HEAs), along with Multi-principal element alloys (MPEs) and Complexly concentrated alloys (CCAs), offer an exciting, emerging branch of materials research. Unlike conventional alloys, which are usually based on one principal element that, to a large extent, determines the properties of the alloy, these types of alloys consider a wide variety of elements, opening a new field for vast compositions and microstructures, making research into HEAs, MPEs and CCAs tremendously compelling.

Elements in the TCHEA databaseConsidered to be only 12 years old, these complex alloys were introduced in 2004 in two papers that were published a mere two months apart. The definition of HEAs, MPEs and CCAs varies, but in the broadest sense, HEAs are considered to be alloys consisting of five or more principal elements with 5 to 35 atomic percentage for each and based on a simple solid solution, while MPEs and CCAs are considered to be alloys with two or more principle elements.

Free OECD-NEA Nuclear Database

AtomIn December 2014, the OECD-NEA will make available a free thermodynamic database applicable to nuclear materials.

This internationally recognised thermodynamic database, TAF-ID, was created in a joint project among 9 organisations, representing 6 member countries: Canada (AECL, RMCC, UOIT), France (CEA), Japan (JAEA, CRIEPI), The Netherlands (NRG), the Republic of Korea (KAERI) and The United States (DoE).
