Maurine Montagnat, Inside a deep ice core. From small scale processes to large scale flow

Maurine Montagnat

Maurine Montagnat conducts her research at Institut of Geosciences of Environment (CNRS and University Grenoble Alpes). She focuses on the understanding and modeling of fundamental mechanisms of ice (snow and firn) deformation, from the dislocation to the ice sheet scale. Her work stands on strong collaborations with the Earth science and metallic material communities to share and co-develop experimental and modeling tools (Digital Image Correlation, EBSD, Xray tomography, Full-field modeling, Finite Element, etc.). She is currently at the Center for Snow Studies (CEN CNRM Météo-France, Grenoble) to explore this porous or evolutionary granular material that is snow.



Early Career Researcher Awards

Following the same spirit as ICAA16 in Montreal, six awards will be distributed to early career researchers on the basis of the quality of their scientific research and on their ability to communicate these results.

Three of these awards have been attributed to PhD students (or having defended their thesis after Nov. 1st, 2018), and three have been attributed to post-doctoral researchers having defended their thesis after Nov. 1st, 2015.

The awardees will give a 15 minutes plenary talk during the conference.

Thomas Klein : “In situ alloying of aluminium-based alloys by (multi-)wire-arc additive manufacturing”

Thomas Klein

Dr. Thomas Klein graduated in Materials Science from the Montanuniversität Leoben, Austria. In his PhD he worked on the phase constitution and deformation mechanisms of intermetallic gamma-TiAl alloys for aerospace applications. His PhD thesis has received several awards including the Theodor Körner award and the DGM-Nachwuchspreis. After his postdoctoral assignment at the Materials Center Leoben Forschung GmbH, Austria, Thomas Klein joined the Light Metals Technologies Ranshofen, Austria, in March 2019 as scientist in the field of alloy and process development for light-metal wire-based additive manufacturing technologies. In his research he focuses on the special requirements of alloys tailored for processing by additive manufacturing.

Huan Zhao

Huan Zhao

Dr. Huan Zhao is working at the Max-Planck-Institut für Eisenforschung (MPIE, Germany) as a postdoctoral researcher. She received her Ph.D. degree at MPIE and RWTH Aachen University in October 2019. The topic of her thesis is Segregation and precipitation at interfaces in a model Al-Zn-Mg-Cu alloy. Prior to that, she obtained her master’s degree in materials engineering from Chongqing University (China) in July 2015. She was a visiting scientist at the Norwegian University of Science and Technology in 2013. Dr. Zhao was honored the Acta Student Award 2018 and the TMS Light Metals Subject Award - Aluminium Alloys in 2019. Dr. Zhao is devoted to unveiling the microstructure-property relationship in structural materials by characterizing the chemistry and structure at the atomic scale using atom probe tomography and electron microscopy.

As a technician at the TEM Gemini Centre, he works on developing transmission electron microscopy techniques, training, and education. His research is connected to the Centre for Advanced Structural Analysis (CASA) at NTNU, where he applies advanced transmission electron microscopy to study the nanoscale of deformed aluminium alloys. This work aims to understand more of how age-hardenable aluminium alloys deform on the nanoscale and provide knowledge that can help improve the foundation of physically based multi-scale modelling frameworks. Currently, he works on understanding the role of precipitate free zones during deformation and fracture processes and how precipitates are sheared during deformation.
