摘要：Synchrotron radiation-based micro-laue technique has showcased great application potentials in materials science study for its unprecedented crystal orientation and lattice strain/stress *** we report the updated progress in the development of the micro-laue technique on the X-ray test beamline at Shanghai Synchrotron Radiation *** far,40μm(h)×50μm(v)X-ray beam spot is routinely obtained,with the convergent angle of 0.2 mrad(h)×0.12 mrad(v).Area scans are conducted on a GH3535 Nibased superalloy base metal and weld joint with the same chemical *** analyzing the tremendous amount of laue diffraction patterns using in-house developed software packages,the crystal orientation,elastic strain,and defect distributions are mapped and *** a successful proof-of-principle study offers first-hand experience on the further optimization of the design and construction of the scanning micro-laue facility on the superbend beamline with improved spatial resolution and multiple functions for simultaneous chemical fluorescence mapping and in-situ microstructural evolution *** micro-laue diffraction beamline at Shanghai Synchrotron Radiation Facility will provide a versatile and powerful tool for the orientation and strain/stress mapping combined with phase identification with micron-sized spatial resolution.
