MT@Micro is a new in-situ Mechanical Testing technology to characterize the microscopic deformation of a material which is built on advanced image processing and machine learning techniques such as image stitching, image stabilization, feature identification and feature tracking to determine various characteristics of microscopic deformation accurately including the strain field, deformation of individual grains/sub-grain features such as their dilatation, distortion, and rotation, the evolution of shear bands and slip lines, micro-twins distribution and their evolution, and more importantly the localization of these quantities around different microstructural feature boundaries.
