Peterson, Real Alloy, USA; and session organizer Arne Ratvik, SINTEF - In addition to the all-conference plenary, the TMS 2018 Annual Meeting & Exhibition (TMS2018) offered a number of invited keynote sessions, programming that highlighted the international aspects of the meeting, and symposia covering special topic areas. The next several pages offer a sampling of what took place in those featured session rooms. that the aluminum industry can be a part of the solution to environmental problems. He noted that his own organization has decreased energy consumption through a combination of technology and management attention. Aalbu was one of six speakers representing various regions of the world who looked at different aspects of sustainability at the session, which explored the theme, Sustainability in the Aluminum Industry: Climate Neutral Industry with Zero Emissions and Zero Waste? TMS2018 Features Distinguished Award Lecturers Three TMS members receiving high-level Society awards delivered featured lectures at TMS2018. Marc A. Meyers, University of California, San Diego, recipient of the Institute of discussed “Biological Materials Science: Challenges and Opportunities”. Zi-Kui Liu, of the William Hume-Rothery Award, delivered the lecture, “Computational Thermodynamics of Materials and Its Applications”. Geoffrey Brooks, Swinburne University of Technology, gave the presentation, “The Revolutions Ahead in their talks on Monday morning. Division Distinguished Lecture Award, Marc A. Meyers Zi-Kui Liu Geoffrey Brooks Magnesium Technology 2018 Keynote Session Karl Kainer, MagIC—Magnesium Innovation Centre, Helmholtz-Zentrum Geesthacht, discussed the lack of knowledge on the potential of magnesium alloys in his talk “Mg Alloys: Challenges and Achievements in Controlling Technology Keynote Session. Kainer explained that the “cost-driven, performance-driven, and corrosiondriven” development of new magnesium alloys aims to increase both creep resistance and castability of the alloys. Currently, high-pressure die-casting is still the dominant technology, as other processes remain too expensive for most types of applications. “This is not necessarily a scientists’ problem;” Kainer noted. “If there is no industry promoting advanced solutions, there is a problem.” While creep resistance is improving, thanks partially to the introduction of rare earth metals, the overall cost is still too high. “This is probably okay for defense applications, but not for automotive,” Kainer said. He also covered a variety of new applications for magnesium alloys, including magnesium air primary batteries for use in anodes. Karl Kainer (speaking) was the first of four speakers who examined new developments in magnesium research and application at the Magnesium Technology 2018 Keynote Session. 2nd International Conference on Computational Design and Simulation of Materials (CDSM 2018) Plenary Session down-to-earth discussion” of how to make the materials that Kuehmann had covered in his presentation. Tong-Yi Zhang of the Shanghai University Materials Genome Institute rounded out the session with his technical presentation, “Theoretical Modeling and Atomistic Thermal Behaviors in Nanomaterials.” The event was introduced by CDSM 2018 co-chair Alan members of the CDSM 2018 organizing committee with a commemorative coin recognizing their contribution to TMS2018. Additive Manufacturing Keynote Session The Additive Manufacturing (AM) Joint Keynote Session drew a standing-room-only crowd for the second year in a row. The session offered attendees a broad overview of AM by geography and material type, while also imagining what the future of AM holds. The of Science and Technology, who presented “Additive Manufacturing Technologies, Applications, Markets and Opportunities.” Leu gave a brief overview of the current world market for AM, noting that while the revenue and unit sales in the United States are growing rapidly, its share of the world market was only 15.5% in 2016. “I think the U.S. will start to increase its share,” Leu said. “U.S. industries will be consolidating, maybe merging, maybe dominating.” Leu also discussed types of AM, including laser foil glass AM by laser-heated deposition, femtosecond laser 3D printing, and 3D bioprinting. Each of these processes has potential applications in the aerospace, automotive, healthcare, and electronics industries. Leu then mentioned the importance of process monitoring and control. “It’s very important to understand the process physics. We are trying to improve [the process], but there Ming Leu discusses the world market for AM in his keynote session talk. innovation, however, is necessary for high-speed, large volume fabrication, advanced biofabrication, and even 4D printing.” Tuesday Featured Sessions Materials and Manufacturing Innovation Keynote Session the big questions of big data during his presentation “Big Data for Materials R&D, Deployment, and Lifecycle” as part of the Materials and Manufacturing Innovation Keynote Session. He was one of four featured speakers who addressed the session topic, Big Data and Machine Learning for Materials. around the phrase ‘big data,’ but it probably isn’t actually used to determine whether or not there is a big data problem. Once the problem is determined and objectives are questions you can ask of the data sets. “We’re dealing with to teach computers to read papers like a materials scientist,” including reading, processing, and understanding data from tables, text, references, and links. These indirect connections materials. However, the data sets are so large they’re inconceivable to the human brain—which is where machine learning comes into play. “Computing is going from decades a research exploration. We’re learning as we go, but we’re seeing great progress.” Jed W. Pietera Looking through the Kaleidoscope: Discovering Your Path to Leadership “Every time there’s an opportunity, I’ve always taken the door and walked through it,” said Michele Manuel, the panel discussion on the topic of minorities in leadership that concluded the symposium, Looking through the Among other points, the panelists highlighted the power of mentors. Manuel was inspired by Greg Olson, Northwestern University, who had also delivered a talk at the Looking through the Kaleidoscope symposium. Amanda Krause, Pictured, from left are panelists Amanda Krause, Lehigh University; Michele Manuel, University of Florida; and Martin Thuo, Iowa State University. Acta Materialia Symposium Three TMS members were honored at the Acta Materialia Symposium, which was organized by Carolyn Hansson, University of Waterloo. The symposium opened with a presentation by George (Rusty) Gray III, Chair and Treasurer/TMS Governor for Acta, on the contributions of Subhash Mahajan, University of California and Acta Materialia Gold Medal recipient. Gray noted that Mahajan, who was unable to attend, has been a long-time mentor to him and provided an overview of Mahajan’s work on deformation twins in metallic crystals. Nikhilesh Chawla, Arizona State University, who received the Acta Materialia Silver Medal honoring leaders aged 45 or under, delivered a presentation on work being done at Arizona State’s new 4-D Materials Science Center. “4-D experiments and correlative microscopy Lehigh University, recalled a high school counselor who pulled her aside and encouraged her when she believed she was not good at science. Given their importance, Martin Thuo, Iowa State University, advised the audience members to spend time researching who they wanted to be their mentors. The value of diversity to the work of an organization was also a recurring theme in the discussion. Thuo said that he doesn’t choose members for his research groups solely based on their grade point average, but rather selects people who think about things in different ways. “Only good things can come of a diverse work group,” he said. Looking through the Kaleidoscope was part of the TMS Student-Run Symposium series, in which a member of the TMS Education Committee mentors students on how to organize a TMS symposium. Organizers for this year’s symposium included Emily Bautista, Mackenzie Jones, Thomas Maulbeck, and Rose Roberts of Virginia Tech. Pictured, from left, are Nikhilesh Chawla, Carolyn Hansson, Rusty Gray (who spoke on behalf of Subhash Mahajan), Julie Christodoulou, and Christopher Schuh, coordinating editor of Acta’s new Materialia journal. are enabling unprecedented insight into a variety of interesting problems,” he said. was honored with the Hollomon Award for Materials materials science and engineering in the era of additive manufacturing. During her presentation, she highlighted the role that Integrated Computational Materials Engineering (ICME) will play in meeting the goals processes more affordable; ICME will help us do that,” she said. Wednesday Featured Sessions FEMS Keynote Symposium project in the United Kingdom, scientists are producing inexpensive perovskite solar panels using screen printers, and using these to create buildings that double as power stations. “Every day more solar energy falls on earth than humanity described the project’s method for producing solar panels as a simple process that doesn’t require a lot of energy, complex equipment, or protective suits. Worsley was one of nine invited speakers who explored the topic of energy and transportation from a European materials perspective during a special, one-day keynote symposium Blademithing Symposium “There’s nothing like the sword,” said Greg Olson, Northwestern University and QuesTek Innovations, as he which served as the keynote talk for the Bladesmithing 2018 Symposium. Olson described the deep respect for swords portrayed in many cultural works, such as Beowulf, noting that this provided him with context as he started research for the DragonSlayer project in 1996. He recounted that he Greg Olson Scientific Publishing Workshop “There is absolutely nothing that any of you can write that cannot be published somewhere,” Suveen Mathaudhu, University of California, Riverside, told participants at Mathaudhu was one of four speakers who addressed excellence as an author, reviewer, or editor, during this special afternoon session, which was open to all TMS2018 attendees. Other featured speakers included Michele a, Santa Barbara. The speakers delivered presentations full of Pictured, from left to right, are speakers and organizers from the FEMS Keynote Symposium: Brett Suddell FEMS Immediate Past President; Donato Firrao, DISAT, Politecnico di Torino, Italy; David Worsley, Swansea University; Timothy Warner, Constellium C-TEC, France; Pedro Dolabella Portella, BAM; David H. DeYoung, 2017 TMS President; Winfried Keiper, Bosch Corporate Research, Germany; David Jarvis, HIPtec, Norway; Marc Fry, Granta Design, United Kingdom. soon discovered the key role of aesthetics; “…new materials processing would be used in art before weaponry,” Olson said, observing that “art is what drives us.” Seeking to replicate a Beowulf-era pattern-welded broadsword, Olson’s team collaborated with various other departments and faculty to ensure accuracy with both history and legend. This approach created a sort of “tech-manities” style of education, as Olson called it. The team explored a variety of high-strength steels, even taking notes from ancient alchemists and integrating meteoric iron (which “made it spiritual, for the aesthetics,” but didn’t necessarily make a “better” blade). Eventually, with no actual dragon to slay in this day and age, blade-on-blade tests were conducted. The modern technology DragonSlayer sword created by the team was tested against a samurai katana, with the DragonSlayer penetrating about .25” into the katana—unscathed. As Olson said: “If you want to project a millennium ahead, you have to back up two.”
