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

Application Notes

Evaluating parent grain reconstruction in Titanium using high temperature in-situ EBSD

Learn how parent grain microstructures can be reconstructed from low temperature EBSD analyses using AZtecCrystal. Here, the reconstruction results for a Titanium sample are tested using in-situ EBSD analyses of beta-Ti collected at >900 °C using a new type of high temperature phosphor screen. The results indicate an excellent agreement between the as-measured and reconstructed beta-Ti microstructures.
