Ravi Ravindran, FASM Professor of Advanced Materials Ryerson University, Toronto “Glimpses of Advances and Chal- lenges in Lightweighting Impacting the Transportation Sector” The transportation sector ac- counts for almost 15% of global greenhouse emissions, and the con- sequent environmental and health effects are significant. Government legislation in the U.S. (and similar standards worldwide) have stipulated a cor- porate average fuel economy (CAFE) of 4.32 L/ 100 km (54.5 US MPG) by 2025. Fossil fuel depletion, environmental consideration and the future of humankind have spurred a global quest for next-generation vehicles. The direct conse- quence is lightweight and energy efficient automobiles. Low density and lightweight alloys and composites of alumi- num (2.7 g/cm 3 ) and magnesium (1.74 g/cm 3 ) have replaced ferrous materials such as steel and cast irons (7.8 g/cm 3 ) in automotive power train components in order to increase fuel efficiency. However, light alloy component develop- ment faces challenges in alloying, solidification process- ing, microstructural development, thermal properties, and in-service performance. Interestingly, significant progress has been made in the mitigation of many challenges, and the journey continues. This lecture provides glimpses of mitigation, related mechanisms, and opportunities for the future. 2020 ASM/TMS Distinguished Lectureship in Materials and Society Dr. Charles H. Ward, FASM Director United States Air Force, Wright Patter- son AFB, Dayton, Ohio “Integrating Materials and Manufacturing” Innovations in digitally-centric technologies continue to progress at a breathtaking pace and are impacting all aspects of our daily and professional lives. Inherently empowered by these advances, Integrated Computational Materials Engineering (ICME) and the Mate- rials Genome Initiative (MGI) have helped transform the way in which we approach materials discovery and devel- opment, with a goal of delivering model-based definitions of materials and processes to be used in design, manufac- ture, and operation. Virtually concurrent with the launch of ICME and MGI, and equally fueled by advances in digital technologies, Digital Manufacturing, or Industry 4.0, seeks to securely flow rich component data through the manufac- turing supply chain to digitally-native manufacturing equip- ment on the shop floor to accelerate production and enable novel designs while decreasing cost and enhancing product quality. This talk will focus on how the application of dig- ital technologies in both materials and manufacturing are creating new opportunities to bring the two communities together. 2020 Edward DeMille Campbell Memorial Lecture Dr. Mrityunjay Singh, FASM Chief Scientist, Ohio Aerospace Institute, Cleveland “Additive Manufacturing: Disrupting Global Supply Chains and Enabling Sustainable Development” The integration of new materials and innovative manufacturing tech- nologies into product supply chains is critically needed to address human and societal needs and to promote sustainable development and economic competitiveness. Recently, there has been tremendous growth in the addi- tive manufacturing (AM) landscape with the introduction of high-end machines suitable for industrial applications. In addition, availability of desktop 3D printers as well as open source printers and platforms have also facilitated the large-scale growth of distributed manufacturing. The paradigm shift in thinking, where one can turn their design into product on demand, is leading to new business models and challenging traditional models of product development and distribution. In this presentation, an overview of differ- ent AM technologies will be provided along with technical challenges and opportunities. Various examples of materi- als (polymers, ceramics, metals, hybrids, and multi-mate- rial systems) and structures achieved from utilizing a wide variety of additive manufacturing approaches will be pro- vided. Technical challenges and opportunities for the use of additive manufacturing as a powerful enabler for sustain- able development and a disruptive technological threat to global supply chains for different materials and systems will be presented.
