Abstract Scope |
High Energy X-ray Diffraction (HEXD) experiments - conducted at a synchrotron x-ray beamline - have evolved enormously since their introduction over two decades ago. Enhanced area detectors and greatly increased x-ray flux at the x-ray beamline have made seemingly impossible experiments possible. Raw HEXD data, which are literally a list of intensities associated with each detector pixel number, are encoded with valuable structural and mechanical information from multiple size scales and locations within a sample. Material modeling results are often compared to HEXD data but many times models are needed for even the most basic interpretation of the HEXD data. This talk describes several model/HEXD data scenarios from experiments conducted on polycrystalline metals over the past several years at the Cornell High Energy Synchrotron Source (CHESS) and the Advanced Photon Source (APS) examining processes such as plasticity, fatigue, residual stress and hydrogen embrittlement. |
