Symposium High Entropy Alloys IX: Structures and Modeling
Presentation Title The Application of High-throughput Calculations in High Entropy Alloys
Author(s) Yu Zhong
On-Site Speaker (Planned) Yu Zhong
Abstract Scope There have been extensive investigations in the last two decades on the high entropy alloys (HEAs). However, it is hard to predict the composition window for the next-generation HEAs by its multicomponent nature. In the current talk, we will go through our recent progress on the high throughput (HT)simulations based on the CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) approach and combined with machine learning. At first, we will discuss the details of the customized procedure we developed on the HT simulations. Then we will focus on its application in high entropy alloys, including how to find the multicomponent eutectic compositions targeting the eutectic high entropy alloys (EHEAs) and bulk metallic glasses (BMGs), and the composition window for the Transformation induced plasticity (TRIP) HEAs and Twinning induced plasticity (TWIP) HEAs.
