ACerS Edward Orton Jr. Memorial Lecture
Sergei V. Kalinin, Weston Fulton Chair Professor, University of Tennessee, Knoxville
Presentation Title: "Microscopy is All You Need: The Rise of Autonomous Science"
About the Presentation
Making microscopes automated and autonomous is a North Star goal for areas ranging from materials and ceramics science to condensed matter physics – with the dream applications of discovering structure-property relationships, exploring physics of nanoscale systems, and building matter on nanometer and atomic scales. Over the last several years, increasing attention has been attracted to the use of artificial intelligence (AI) interacting with physical system as a part of active learning – including materials discovery and optimization, chemical synthesis, and physical measurements. For these active learning problems, microscopy arguably represents an ideal model application combining aspects of materials discovery via observation and spectroscopy, physical learning with relatively shallow priors and small number of exogenous variables, and modifications. In this presentation, Kalinin will illustrate the examples of fully autonomous microscopy systems for exploring grain boundary transport behavior in polycrystalline materials, discovering the origins of non-linearity, nucleation biases, and work of switching in ferroelectric materials, and discovery of the ferroelectric domain growth laws. The same algorithms can be deployed on the electron microscopes for the discovery of the regions of interest based on their EELS signatures. These workflows are further developed to allow for explainable AI and human in the loop interventions. Overall, the development of advanced machine learning methods now opens a pathway to complete overhaul of classical operational concepts in microscopy, enhancing its potential for scientific discovery across multiple disciplines.
About the Presenter
Sergei V. Kalinin is the Weston Fulton Chair Professor at the University of Tennessee, Knoxville. From 2022-2023, he spent a year at Amazon (special projects) as a principal scientist, following 20 years at Oak Ridge National Laboratory
(ORNL). He received his M.S. degree from Moscow State University in 1998 and Ph.D. from the University of Pennsylvania (UPenn) in 2002. Kalinin has co-authored over 650 publications, approximately 50,000 total citations, and an h-index of ~110. He is a fellow of MRS, APS, IoP, IEEE, Foresight Institute, and AVS; a recipient of the Blavatnik Award for Physical Sciences (2018), the Medal for Scanning Probe Microscopy (2015), the Presidential Early Career Award for Scientists and Engineers (PECASE) (2009), the Burton Medal of Microscopy Society of America (2010), and four R&D100 Awards (2008, 2010, 2016, and 2018); and a number of other distinctions. Kalinin got introduced to scanning probe microscopy at UPenn working with Dawn Bonnell. At ORNL, he built the SPM program at the Center for Nanophase Materials Sciences, pioneering several new SPM techniques and applications such as band excitation and G-Mode SPM, electrochemical strain microscopy, and big data SPM modes. While at ORNL, he was introduced to scanning transmission electron microscopy by Steve Pennycook. As the inaugural director for the ORNL Institute for Functional Imaging of Materials (IFIM, 2014-2019), he and his team worked on bridging physical and chemical imaging and artificial intelligence. For the last 15 years, his research has focused on the applications of machine learning and artificial intelligence in nanotechnology, direct electron beam atomic fabrication, and materials discovery via scanning transmission electron microscopy, as well as mesoscopic studies of electrochemical, ferroelectric, and transport phenomena via scanning probe microscopy.
AIST Adolf Martens Memorial Steel Lecture
Keith Taylor, Principal Research Engineer, R&D Department, SSAB Americas
Presentation Title: "Practical Applications of Physical Metallurgy to Industrial Steel Product Development"
About the Presentation
Product development is something not taught in most university materials science programs but is available as a professional pursuit during employment after graduation. For a product development to be a commercial success (i.e., profitable), there has to be demand for the product, processing requirements for the product must be compatible with production facilities, and the margin between selling price and production cost should be above some suitable threshold. This presentation will highlight some metallurgical aspects of steel product development, including heat-treated martensitic steel plate products, based on the presenter’s own experiences in this area. Topics include alloy design considerations and tools, laboratory heat treatment simulation, alloy enrichment at grain boundaries, product testing, and microstructural characterization.
About the Presenter
Keith Taylor is a principal research engineer with SSAB Americas’ R&D department. In this role, he has been responsible mainly for developing heat-treated steel plate products. He has led the SSAB commercial product development team since 2010 and contributed to the development of approximately 110 new products. Prior to SSAB, he worked for GE Aircraft Engines as a materials application engineer where he was responsible for metallurgical support relating to various turbine engine components including main shaft bearings, carburized gears, and legacy engine rotating parts. The first 20 years of his career were spent at Homer Research Laboratories, part of the former Bethlehem Steel Corp., and the later part at the International Steel Group (ISG) and Mittal Steel. He progressed from research engineer working on steel plate and heavy forgings, to senior research engineer working on cold-rolled products, to research supervisor managing a group of 11 working on light flat-rolled products.
Over the years, Taylor has been active on many committees. He served as the Bethlehem/ISG representative on ASTM steel committees and chairman of the ASTM Steel Sheet and Strip subcommittee. He has been the SSAB representative on the Industrial Advisory Board of the Colorado School of Mines Advanced Steel Processing and Products Research Center. He has been active on the TMS Ferrous Metallurgy Committee, the ISS Product Physical Metallurgy Committee (PPMC), and the AIST Metallurgy – Processing, Products & Applications Technology Committee (MPPATC). For TMS, he was the main organizer of an international symposium on the Physical Metallurgy of Direct-Quenched Steels and co-edited the conference proceedings. For ISS PPMC, the predecessor of the AIST MPPATC, he chaired the committee for three years and organized symposia.
Taylor is a graduate of the Massachusetts Institute of Technology (MIT) with an S.B. in materials science and engineering and a Sc.D. in metallurgy, and he is a licensed Professional Engineer. He has 32 publications and was granted two U.S. patents. Some of his awards include: the Charles Hatchett Award for Best Paper on the Use of Nb, the Vanadium Award for Best Paper on the Use of V, and the Engineer of Year Award from the Lehigh Valley Chapter of the Pennsylvania Society of Professional Engineers.
TMS Plenary Speaker
Alan A. Luo, Professor of Materials Science and Engineering and Integrated Systems Engineering, The Ohio State University (OSU), and Director of OSU Lightweight Materials and Manufacturing Research Laboratory and Advanced Casting Research Center
Presentation Title: "Lightweight Materials and Sustainable Manufacturing: The Role of Integrated Computational Materials Engineering (ICME)"
About the Presentation
Lightweight materials including aluminum, magnesium, titanium, and metal matrix composites are increasingly being used in the transportation and manufacturing industries to reduce energy consumption and carbon footprint. Emerging materials including high entropy alloys, bioresorbable magnesium alloys, and densified superwood materials are also promising in new engineering and biomedical applications. Integrated Computational Materials Engineering (ICME) is defined as the integration of materials information, captured in computational tools, with engineering product performance analysis and manufacturing-process simulation. This talk presents some examples of lightweight material design and development using a CALPHAD-based ICME approach. The presentation will also discuss some of the latest innovations in sustainable casting, extrusion, sheet forming, and multi-material manufacturing processes. Microstructure models for light alloys have been developed based on computational thermodynamics and kinetics, coupled with manufacturing process models. These ICME models are integrated to predict location-specific mechanical properties, based on location-specific microstructure of solidification (casting, welding, and additive manufacturing) products.
