Description:
Author(s): Maarten de Jong, Liang Qi, David L. Olmsted, Axel van de Walle, and Mark Asta The process of deformation twinning, as schematically indicated in the figure, plays an important role in establishing the ductility of many engineering materials such as titanium and magnesium and some refractory alloys. By fine tuning alloy compositions, the tendency for twin formation can be controlled, which can lead to guidelines for design of advanced alloys for applications spanning biomedical, energy conversion, and high-temperature structural applications. This work presents a theoretical framework to computationally study the effect of alloying on planar defect energies and is expected to be a useful tool for computationally guided alloy design.
