Abstract:
In-situ X-ray diffraction is a powerful technique for investigating the dynamic behaviors of polycrystalline materials. Recent advances in X-ray sources and detectors have significantly improved data acquisition, enabling the capture of transient lattice changes during rapid processes. My research on Ni-alloy 718, utilizing in-situ synchrotron X-ray diffraction, revealed the rapid development of thermal and mechanical strains during laser processing. Additionally, I examined the phase evolution of martensite (α') in Ti-6Al-4V during rapid cooling and heating, which allowed for temporally resolving α' formation and decomposition during laser processing. This presentation also highlights the potential of laboratory-scale high-energy diffraction microscopy (HEDM), a technique traditionally limited to synchrotron facilities.
