In situ high-energy synchrotron X-ray diffraction reveals the role of texture on the activation of slip and twinning during deformation of laser powder bed fusion Ti–6Al–4V

The deformation behavior of Ti–6Al–4V processed by laser powder bed fusion (LPBF) is investigated by in situ high-energy synchrotron X-ray diffraction (HEXRD) during uniaxial compression. The initial microstructure of the alloy consists of a fine lamellar a¿+¿ß microstructure where a lamellae are se...
