Many of the physical properties of metal powders, such as powder densification and strain hardening, are strongly dependent on the materials properties of the individual particles. Therefore, the microstructural characterisation of metal powders, providing information about particle grain size, texture and deformation, is of paramount importance yet is significantly lacking in the field of additive manufacturing.
SEM based electron backscattered diffraction (EBSD) is a fast, automated technique that provides information about the crystallographic orientation and phase on the surface of a sample with sub-micrometre resolution. Unlike other characterisation techniques, EBSD provides statistically-relevant data from large areas on the sample surface but also enables detailed spatially-resolved variations to be observed.
