As the third International Workshop on High Entropy Materials was organized by the Department of Materials Science & Engineering in Kanpur India, three weeks ago, Thermo-Calc software and TCHEA databases enjoyed a host of references to the opportunities created by computerized applications. At a vibrant and compelling gathering of great minds, Bhanu Prasad Babburi, Director at Bhanu Scientific Systems and the Thermo-Calc Software agent for India, participated.
Genuine Interest in High Entropy Alloy (HEA)
At the event, there was a lot of focus on HEA and computational tools.
“There were a lot of presenters who referred to Thermo-Calc software and the TCHEA databases”, Bhanu Prasad Babburi relays.
This is to no surprise, as HEA research is of high interest for scientists, engineers and researchers, yet not fully converted to industrial scale production or big scale manufacturing. Niched areas such as aerospace nuclear and space, are beginning to produce small and critical parts. Thus, it is of high importance to understand the properties of materials, and to create a foundation for further research and development. Thermo-Calc software and TCHEA databases are used to understand the material properties and reduce cost of research by avoiding trials.
“Thermo-Calc software and TCHEA databases have proven to be very useful tools, for the results agreed with experimental values. Indian scientists, who endeavor to replace traditional materials with HEA, are finding that it is working out”, Bhanu Prasad Babburi confirms. “As High Entropy Materials in India are in preliminary stages, scientists are finding different grades of materials for different applications. Both computational and conventional methods of material development is taking place in India, and the usage of computational tools are indispensable”.
CALPHAD methodology Used for Developing Alloys
As researchers and scientists presented their posters, Bhanu Prasad Babburi witnessed that the CALPHAD methodology of developing alloys, as well as mechanical alloying routes and experimental techniques on data generation kept occurring.
In India, and the rest of the world, HEA development is in an evolving stage, and it will be a while before full-time production is possible. Until then, the usage of computational tools is rising by the day. Thermo-Calc software and TCHEA databases are playing important roles, something that the poster presentations at the International Workshop on High Entropy Materials clearly reflected.
The event was hosted 7 – 8 of March by the Indian Institute of Technology Kanpur. The Indian Institute of Metals Kanpur Chapter have several papers published using Thermo-Calc products in a variety of articles.
