Journal Article
Speidel, A., Bisterov, I., Ahmed, S., & Clare, A. T. (2024). Ambient grain orientation imaging on complex surfaces. Acta Materialia, 265, Article 119604. https://doi.org/10.1016/j.actamat.2023.119604

Crystal orientation imaging is generally confined to the laboratory, typically following destructive sectioning, with most current techniques reliant on electron-material interactions that require a vacuum. This information is gathered in a manner th... Read More about Ambient grain orientation imaging on complex surfaces.

Processing of highly reflective and high thermally conductive materials (Cu, Ag, etc.) by laser powder bed fusion (LPBF) is of increasing interest to broaden the range of materials that can be additively manufactured. However, these alloys are challe... Read More about Tailoring absorptivity of highly reflective Ag powders by pulsed-direct current magnetron sputtering for additive manufacturing processes.
