Potential of Small Scale Testing Techniques to Enhance Development of Energy Related Matierals:
Carbon neutral forms of energy, such as fusion or fission, require development of new materials capable of sustaining the harsh environment in such reactors. Especially new reactor concepts or lifetime extension programs demand a basic understanding of the materials in use as well as covering a wide range of datasets. Classical material development is a timely and expensive process involving neutron exposure in testing reactors, and radiation facilities designed for high dose materials irradiations are not easily available today. Therefore, scientists and engineers seek new methods to irradiate and test materials to understand fundamental aspects of radiation damage, aiding the development of predictive models. In this presentation, we will address possibilities of alternative irradiation processes such as proton or ion irradiation in combination with small scale testing methods performed in-situ in electron microscopes. Utilizing this approach, we can enhance the understanding of dislocation based deformation in irradiated materials while scoping the “limit of scale” on small scale mechanical testing on the surrogate material copper. The methods of small scale mechanical testing on ion beam irradiated materials are introduced and basic material science processes are discussed.

About Daniel Kiener, Ph.D.:
Dr. Daniel Kiener received his PhD in materials science at the Montanuniversität Leoben, Austria. After holding post-doc positions in Munich and Berkeley, he returned to the Montanuniversität Leoben as an assistant professor in the Department of Materials Physics. His research interest focuses on the field of small scale mechanics, aiming to understand size effects and strengthening mechanisms in miniaturized samples. In particular, Dr. Kiener is renewed for developing quantitative in-situ testing methods in the scanning and transmission electron microscope. The significance of his work is reflected by the recognition in the community (Most cited article since 2008, Acta Materialia; Top cited Author 2011, Materials Science and Engineering: A) and was awarded multiple times, for example with the Fritz-Kohlrausch prize, the highest physics award of the Austrian Physical Society.
