(See “50 Years of High Impact Research”.) Known then as Metallurgical Transactions, the journal has earned a reputation for excellence over the last 50 years. Building on its respected past, Metallurgical and Materials Transac- tions (MMT) considers what changes the future will bring. Tresa Pollock, FASM, principal editor, and her edito- rial teamwere asked their views of how the journal might evolve over the next 50 years. Their responses speculate that the journal’s strengths over the last 50 years will guide its course for the future as materials, processes, and applications advance. New Materials and Processes With tools for discovery rapidly evolving, there will undoubtedly be new classes of materials discovered that will receive a great deal of attention. “New approaches to processing also seem to continuously appear, and additive manufacturing will be a major topic in the next few years,” says Pollock. “WITH THE TOOLS FOR DISCOVERY RAPIDLY EVOLVING, THE UPCOMING YEARS WILL UNDOUBTEDLY BE RICH WITH NEW ALLOYS AND APPLICATIONS.” — POLLOCK Development of advanced mate- rials processing will be critical to challenges such as climate change, energy, mobility, and safety, says Mat- thias Militzer. “Here MMT will have the opportunity to be at the forefront,” he adds. “There is a particular emphasis on materials processing that sets MMT apart from other materials journals.” New research topics may include the fields of powder metallurgy (near net-shape forming, new sinter- ing techniques), advanced solidifi- cation techniques, and graded materials/structures, according to Jonathan Cormier. “I also feel that the area of composite materials processing/properties, espec- ially for metallic based composites, will grow in the near future,” he adds. “MMT IS WELL-POSITIONED TO INCREASINGLY TAKE LEADERSHIP IN BRIDGING BETWEEN ACADEMIC RESEARCH AND INDUSTRIAL APPLICATION.” — MILITZER “Each of these new develop- ments would require fundamental understandings in the areas that are currently covered in MMT, such as microstructures and mechanical prop- erties,” says Jian-Feng Nie. He adds that processing-microstructure-prop- erty relationships in metallic alloys will remain a staple of MMT, no matter what new materials or innovative manufac- turing technologies will be invented. “Light alloys such as magnesium and aluminum are expected to expand their applications and market share for more energy efficient and environmentally friendly applications,” he says.

Matthias Militzer, University of British Columbia, Vancouver, Canada Jian-Feng Nie, Monash University, Melbourne, Australia “TOPICS SUCH AS PROCESSING- MICROSTRUCTURE-PROPERTY RELATIONSHIPS IN METALLIC ALLOYS WILL SURELY STAY IN THE MMT MIX, NO MATTER WHAT NEW MATERIALS OR INNOVATIVE MANUFACTURING TECHNOLOGIES WILL BE INVENTED.” — NIE Integrated Computational Materials Engineering (ICME) and Modeling Overwhelmingly, the editors say that modeling, com- putational power, and a data-driven approach will shape the journal’s content for the foreseeable future. “The trial and error approach to obtaining new materials processing techniques will become obsolete,” says Il Sohn. “Filtering
