Additive Manufacturing

Additive manufacturing (AM) is a rapidly growing field in which Electron Backscatter Diffraction (EBSD) is playing an important role. The development of multiple new approaches to the manufacture of high-performance materials results in microstructures that differ significantly from more conventional manufacturing processes. These microstructures need to be characterised in order for researchers to understand the influence of the AM process parameters on the physical properties of the final component. EBSD is the ideal technique for this, providing information on the grain structure, phase distribution, texture, boundary properties and localised strain

Examples of EBSD application in additive manufacturing includes:

EBSD orientation maps from an additively manufactured Ti64 alloy
