Future Forward: The Next Century of Materials Innovation As part of ASM InternationalÕs 100-year anniversary (1913-2013), our yearlong timeline series explores the history of ASM and materials science and engineering in 10-year increments. The final timeline appeared in our October issue. We now conclude our celebratory year with a look toward the future. In this special roundtable, five ASM thought leaders share their perspectives on what the next 100 years of materials science and engineering might look like. Nobody has a crystal ball, but what do you believe are the most promising areas of materials engineering R&D for the next few decades? Al Romig: There's a long runway ahead for materials with special properties where electrons and photons can be manipulated to achieve different purposes. This will have a big impact on things like electronic devices and sensor applications, and with new metamaterials where photons can be manipulated in unusual ways. Another promising area involves materials for high temperature, high speed applications. We're on the brink of hypersonic flight and we need materials for propulsion systems and other structures that can handle this environment. We're now exploring a whole range of materials never used before for exit and re-entry in the space realm, such as advanced ceramics. Another big drive is to achieve greater and greater specific material properties, such as strength or toughness, per equivalent weight. The need for higher energy efficiency will drive these lightweighting efforts in the automotive, air, and space transportation arenas. Diran Apelian: I believe we are entering a new era of materials science and engineering (MSE), as many of the world's societal issues have solutions embedded in MSE. With world population increasing at an annual rate of 1.4% and our thirst for energy increasing at 1.7%, we need materials solutions to implement renewable energy. Our mobility needs will require lighter and stronger materials 2013 Images courtesy of University of Pennsylvania, CERN, NASA, Zugaldia, IBM, Purdue University, and the Smithsonian (in order of appearance).
