Metals are widely used for load-bearing applications in complex environments. Their properties are dependent on the underlying behaviour of the material microstructure, which is naturally anisotropic due to the discreet and crystallographic nature of slip and anisotropic elastic properties. This project focuses on developing efficient methods of modelling the evolution of crystallographic texture in two-phase alloys using efficient crystal plasticity based upon the fast Fourier transform. Working with Rolls-Royce plc, materials will be characterised using HR-EBSD to determine textures which will further stimulate the computational work.

金属广泛用于复杂环境中的承载应用。它们的特性取决于材料微观结构的基本行为，由于滑移和各向异性弹性特性的离散和晶体学性质，材料微观结构自然具有各向异性。该项目的重点是开发有效的方法，利用基于快速傅里叶变换的高效晶体塑性来模拟两相合金中晶体织构的演化。与劳斯莱斯公司合作，将使用 HR-EBSD 来表征材料以确定纹理，这将进一步刺激计算工作。
