Abstract Scope |
Transformation/twinning-induced plasticity (TRIP/TWIP) significantly impact material properties like strength and ductility in alloys. Stacking fault energies (SFE) play an essential role in determining TRIP/TWIP mechanisms, and thus a close examination of SFE is crucial for predicting and controlling the mechanical properties of TRIP/TWIP alloys. In the current work, we investigate TRIP/TWIP in high entropy alloys (HEA) by modeling stacking fault energies. The intricate nature of phases present in HEAs gives both opportunities and challenges in material design. Therefore, we will use a high throughput approach with computational methods to effectively and efficiently calculate the stacking fault energies and then determine the plastic deformation mechanisms through numerous compositions. With the high throughput results, we can comprehensively understand TRIP/TWIP in high entropy alloys and improve material designs. |
