<i>In-situ</i> Tensile Tester for Scanning Three-Dimensional X-ray Diffraction Microscopy

Abstract

Understanding of deformation and degradation of bulk metals under loading is necessary to improve the safety and environmental performance of mechanical components such as automobile parts. One of the key parameters in mechanical characterization is strain. Large strains that affect reliability can often be measured as changes in the crystallographic orientation. Electron backscatter diffraction (EBSD) method can measure strains only on the sample surface. However, since strain distribution varies under constrained conditions, nondestructive measurement inside the material is necessary to determine the actual mechanical response of the material.
