Invited Speakers

Silvère Akamatsu
Sorbonne Universitè, France

As a senior researcher (CNRS), I conduct my research at Institut des Nanosciences de Paris (INSP), Sorbonne University, Paris, France. My main field of investigation is the formation dynamics of solidification patterns by in situ experimentation, using model transparent and metallic alloys, mostly in thin samples. The fundamental motivation is to address complex microstructure selection problems of strong impact in materials science, under the light of the nonlinear physics of nonequilbrium pattern forming systems. Current focus is on lamellar and rod-like eutectics in isotropic/anisotropic systems, combining real-time optical observation methods and crystallographic analysis. I work in collaboration with metallurgists, experimentalist physicists, and theoreticians with a strong expertise in numerical simulations.

Tyson Back
Air Force Research Laboratory, USA

Research involves the development of next generation cathode and anode materials for use in high power vacuum electronic applications.  A wide variety of surface analysis methods are being utilized to evaluate fundamental electron emission mechanisms associated with candidate materials such as directionally solidified eutectics.   Recently, we have begun to employ emission microscopy methods to observe the electron emission process in real time.  With emission microscopy, electron emission can be imaged at nanometer scales under various temperatures and electric fields, which more closely represent the true behavior of a working cathode. 

Abhik Choudhury
Indian Institute of Science, India

My research typically focuses on understanding pattern formation during phase transformations such as solidification and precipitation using a combination of controlled experiments and phase-field modeling. In particular, our group has focussed on binary/multicomponent eutectic reactions. We utilize an in-house fabricated modified Bridgman furnace for conducting experiments and state-of-the-art phase-field models for modeling microstructure evolution. In addition, our group works on phase-field model developments for other phenomena, such as electromigration and corrosion. The present funded research in my group is related to aspects of single-crystal growth of superalloys using classical directional solidification and additive manufacturing. Finally, our group is part of a consortium involved in developing an open-source phase-field software MicroSim.

Jianrong Gao

Prof. Gao is interested in theory and in situ diagnosis of non-equilibrium solidification of metallic materials under extreme conditions. His group uses high-speed optical imaging to investigate crystal growth kinetics and thermoelectric magnetohydrodynamic flow effect during rapid solidification of pure metals, binary and multicomponent alloys at high undercoolings and high magnetic fields. His group also uses synchrotron X-rays to investigate in situ phase transformation behavior of structural and functional materials towards an understanding of metastable microstructure formation and complex structure-property relationship.

Sheng Guo
Chalmers University, Sweden

Sheng Guo’s current research interests are with physical metallurgy of high entropy alloys (HEAs), also known as compositionally complex alloys (CCAs).  At the moment, he mainly works on two types of HEAs, eutectic HEAs (EHEAs) and refractory HEAs (RHEAs), both for structural applications. He is also getting into the field of additive manufacturing (AM), using AM not only as a new processing route, but also as a way to tune the micro-structure and phase constitutions.

My research interests focus on alloy design, microstructure formation and material properties for cast and additively manufactured metallic materials.
