2020 TMS Annual Meeting & Exhibition: Advancing Current and State-of-the-Art Application of Ni- and Co-based Superalloys: Organized by Chantal Sudbrack; Mario Bochiechio; Kevin Bockenstedt; Katerina Christofidou; James Coakley; Martin Detrois; Laura Dial; Bij-Na Kim; Victoria Miller; Kinga Unocic

Superalloys are critical to operation and future design of a wide variety of propulsion and power generation components in the aerospace, marine, and energy industries. Their industrial application is often driven by excellent long-term stability and durability at elevated temperatures or in aggressive environments because they display a good balance of mechanical strength, fatigue and creep resistance, as well as corrosion and oxidation resistance. The symposium aims to attract papers on current and state-of-art application of Ni- and Co-based superalloys. Topics of interest may include (but are not limited to): • Viability of fabrication with additive manufacturing methods (powder bed techniques and direct energy deposition) • Relationships of metallurgical processing with microstructure and performance (i.e. casting, forging and heat treatment) • Mechanisms of ambient and elevated temperature plasticity, creep, fatigue, creep-fatigue, crack growth and environmental damage • Mitigation of environmental, thermal, and thermal mechanical damage, including improved coatings for service operation • Advancement in joining, repair, and rejuvenation of superalloys

2020 TMS Annual Meeting & Exhibition: Materials Design Approaches and Experiences V: Organized by Akane Suzuki; Ji-Cheng Zhao; Michael Fahrmann; Qiang Feng; Michael Titus

This symposium is a continuation of four previous successful symposia held at TMS annual meetings in 2001 (Indianapolis), 2006 (San Antonio), 2012 (Orlando) and 2016 (Nashville). It serves as a periodic review of the state-of-the-art development on the subject. In this symposium, we will bring together materials scientists and engineers to share their experiences, including successful and unsuccessful examples, challenges, lessons learned, in developing wide variety of class of alloys for industrial applications, as well as new tools and methodologies that enable efficient alloy design and accelerated implementation processes. The interaction between the two groups will bridge the gaps between them, thus accelerating the transition of new design tools to alloy development. Covering both past experiences and new approaches – both experimental and computational, this symposium will also help identify some critical areas/needs in new methodologies/tools for the community to focus upon. Applications of artificial intelligence and machine learning to alloy design are one of the new areas of interest in this symposium.

2019 TMS Annual Meeting & Exhibition: Deformation and Damage Behavior of High Temperature Alloys: Organized by Michael Titus; Qiang Feng; Akane Suzuki; Jonathan Cormier; Sammy Tin; Martin Detrois

High temperature alloys are critical to the design and operation of a wide variety of industrially important systems including those for propulsion, power generation, petro-chemical processing and more. To improve the performance and efficiency of these systems, operating temperatures, stresses and environmental conditions are becoming more extreme and many of the key structural materials are now being used near the limit of their temperature capability. As a result, understanding the characteristic deformation behavior of these high temperature structural materials during service is important for component life prediction and the development of new alloy systems. In addition, the characteristic deformation behavior of these materials also impacts their processability and formability (or manufacturability). For example, mitigation of thermally induced stresses during additive manufacturing/welding or optimization of thermal-mechanical processing parameters for forming operations also requires knowledge of the characteristic deformation behavior associated with high temperature alloys. Advances in this field are key to the high temperature structural materials community as they serve to drive research and development on an industrially relevant and scientifically challenging topic. The symposium aims to highlight recent advances in understanding, quantifying and/or modeling deformation in various high temperature metallic alloy systems (Ni, Co, Fe and CCA/HEA based alloys). Focus areas of this symposium include, but are not limited to, the development of new alloys, characterization/testing techniques, ICME studies, property models and methodologies, etc. related to deformation, long-term stability and damage mechanisms in high temperature alloy systems.

2019 TMS Annual Meeting & Exhibition: Gamma (FCC)/Gamma-Prime (L12) Co-Based Superalloys III: Organized by Michael Titus; David Dye; Eric Lass; Katelun Wertz; Christopher Zenk

The report of a stable \\947;’-L12 phase in the ternary Co-Al-W system in 2006 has given rise to significant research on a new class of precipitation strengthened alloys, analogous to Ni-based superalloys which are often utilized in high temperature turbine engine components. Since the initial discovery, a myriad of Co- and CoNi-based alloy compositions have been developed with proposed applications ranging from high pressure turbine blades to compressor disks. However, significant challenges still exist for commercial transition of these new alloys, including increasing the \\947;’-solvus, improving oxidation resistance, characterizing fatigue resistance, and establishing processing windows. This symposium continues in the tradition of the first two TMS symposia on \\947;-\\947;’ Co-based superalloys (held in 2014 and 2017) to bring together the growing community of researchers involved with developing \\947;’ -strengthened Co-based superalloys for high temperature and other applications. Experimental and computational investigations on Co- and CoNi-based alloys�that�focus�on understanding materials response, use ICME-based�approaches,�or�aid in rapid alloy development will be highlighted. Topics of interest include: strategies for increasing the \\947;’ solvus temperature, improving environmental resistance, evaluating high temperature mechanical performance, assessing phase stability and phase transformation mechanisms, and advancing processing methods of these promising new materials.

This symposium focuses on ICME case studies and experimental validation of materials for extreme environments. We are seeking abstracts in the following general topic areas, including but not limited to: \\176; Developing and validating ICME approaches for material design, manufacturing process development (including advanced manufacturing techniques), mechanical behavior (e.g., tensile and creep), and environmental performance (e.g., corrosion and/or oxidation resistance). \\176; Performing critical experiments to fill knowledge gaps for physics-based, mechanistic process-structure-property models, elucidating the relationship between environment and the evolution of microstructure. \\176;Developing methods to expedite verification and validation testing of materials for extreme environments and relevant performance models under representative extreme environments. \\176; Demonstrate how this approach can be applied to novel alloys (e.g., high entropy alloys), critical alloy systems (e.g., Ni-based alloys), coatings, novel extreme environments (e.g., supercritical CO2), and/or novel product forms (e.g., thin sheet materials). The proposed four sessions will be carried out over two full days, with morning and afternoon sessions each day. Throughout the four sessions, we anticipate about 30 oral presentations, with 4-8 of those being keynote presentations.

2018 TMS Annual Meeting & Exhibition: Deformation and Damage Mechanisms in High Temperature Ni, Co and Fe-based Superalloys: Organized by Mark Hardy; Kevin Bockenstedt; Chantal Sudbrack; Michael Titus; Kinga Unocic; Yukinori Yamamoto

Ni-, Co- and Fe-based superalloys are enabling materials for the design of high-temperature components for aerospace propulsion, chemical processing, oil and gas applications, and power generation. They retain superior strength at elevated temperatures, and show excellent damage tolerance, toughness, long-term stability and resistance to creep accumulation and environmental damage. The performance of these alloys is often improved when formed to optimize microstructure or used in conjunction with surface treatments and coatings or with novel design solutions. The aim of the symposium is to discuss the mechanisms of deformation and damage in the manufacture and application of high temperature Ni, Co and Fe based superalloys. It is proposed that the technical focus is on the understanding: - Roles of deformation and heat treatment on the evolution of microstructure during material processing - Effects of deformation from manufacture on material and component behavior - Mechanisms of deformation that determine material behavior - Development of deformation that gives rise to damage during material application - Effects of composition and microstructure on resistance to deformation and damage accumulation Topics of interest may include (but are not limited to): - Elevated temperature forging, recrystallization, grain growth, flow forming, machining and shot peening - Experimental observation of deformation and damage accumulation - Constitutive and computational modeling of deformation - Mechanisms of ambient and elevated temperature plasticity, creep, fatigue, creep-fatigue, crack growth and environmental damage
