© 2020 Elsevier B.V. The present work introduces a small volume, high throughput testing method that may be used to quickly, and with high spatial fidelity, investigate local material properties in additively manufactured materials. A case study appl... Read More about On the use of small ring testing for the characterisation of elastic and yield material property variation in additively manufactured materials.

There remains a significant challenge in adapting alloys for metal based Additive Manufacturing (AM). Adjusting alloy composition to suit the process, particularly under regimes close to industrial practice, is therefore a potential solution. With th...

Refinement of the grain structure of additive manufactured titanium alloys via epitaxial recrystallization enabled by rapid heat treatment (2020)
Journal Article
Zou, Z., Simonelli, M., Katrib, J., Dimitrakis, G., & Hague, R. (2020). Refinement of the grain structure of additive manufactured titanium alloys via epitaxial recrystallization enabled by rapid heat treatment. Scripta Materialia, 180, 66-70. https://doi.org/10.1016/j.scriptamat.2020.01.027

The coarse prior-? grain structure in titanium alloys produced by additive manufacturing is associated to mechanical anisotropy and limited fatigue life. Here we report a novel methodology to refine such structure by rapid heat treatment of Ti-6Al-4V...
