This PhD project will look at examining local structural phenomena under applied stress conditions. This project will involve both the examination of particular materials of interest, and the development of an in-situ rig suitable for performing these measurements on the Polaris diffractometer at the ISIS Neutron and Muon Source. Metallurgical samples will be prepared at the University of Sheffield, including powder manufacturing methods, and characterisation of the samples by scanning and transmission electron microscopy. Total scattering data will be acquired at the ISIS Neutron and Muon source, and complementary X-ray data at the Diamond light source. Analysis of these data will be carried out using RMCProfile and PDFGui, as well as developing bespoke analysis code. Tensile testing will be carried out on samples both in-situ and ex-situ.

这个博士项目将着眼于研究在外加应力条件下的局部结构现象。该项目将涉及对感兴趣的特定材料的检查，以及开发适用于在ISIS中子和Muon源的北极星衍射仪上进行这些测量的现场试验台。冶金样品将在谢菲尔德大学准备，包括粉末制造方法，以及通过扫描和透射电子显微镜对样品进行表征。总散射数据将在ISIS中子和Muon源获得，补充X射线数据将在钻石光源获得。将使用RMCProfile和PDFGui对这些数据进行分析，并开发定制的分析代码。拉伸试验将在现场和非现场两种情况下进行。
