In honor of the 150th anniversary of TMS and the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME), TMS has made a series of recorded talks available from the TMS 2021 Virtual Annual Meeting & Exhibition (TMS2021 Virtual), held March 15–18, 2021. Selected by the five TMS technical divisions as Anniversary Keynotes, these talks can now be viewed by all web users at no charge. Access the full presentations below.
Extraction & Processing Division
"Materials Innovations Towards Decarbonization of Industrial Processes"
Elsa Olivetti
Massachusetts Institute of Technology
About the Presentation
This invited presentation was delivered at Design and Manufacturing Approaches for the Next Generation of Sustainable Materials, the 2021 Student-Led Symposium, which was organized by a team of students from the Colorado School of Mines. Olivetti discusses work focusing on strategies to mitigate greenhouse gas emissions in materials-related industries and looks at resource use and the complexity of that process.
"Establishing a Domestic Cobalt Supply Chain: Unlocking Challenging Feedstocks"
Frank Santaguida
First Cobalt Corporation
About the Presentation
This talk was presented at the plenary session for the 5th International Symposium on Nickel and Cobalt (Nickel-Cobalt 2021), a special event held in conjunction with TMS2021 Virtual. This talk looks at the availability of resources around the world and the challenges this poses to the supply chain.
Functional Materials Division
"Current Perspectives in High-Entropy Alloys"
Presenter: Diran Apelian, University of California, Irvine
Co-Authors: Benjamin Macdonald, Cheng Zhang, and Enrique Lavernia, University of California, Irvine
About the Presentation
This keynote presentation from the High Entropy Alloys IX: Alloy Development and Properties symposium at TMS2021 Virtual discusses how the field of high-entropy alloys (HEA) has evolved, examines specific systems and mechanistic opportunities, and looks at future directions for HEA research.
"Designing Electrode Architectures across Length Scales: Some Lessons Learned from Li-ion and ‘Beyond Li’ Chemistries"
Sarbajit Banerjee
Texas A&M University
About the Presentation
This keynote talk from the symposium Advanced Materials for Energy Conversion and Storage VII discusses efforts to develop an Angstrom-level view of diffusion pathways using a combination of single-crystal X-ray diffraction and density functional theory calculations.
Light Metals Division
"Evolution of Alloy Design, Its Science/Instruments Base, Tech Transfer Routes, and Market Pull, 1921-2021"
Raymond Decker
University of Michigan
About the Presentation
This talk was delivered as part of the TMS Light Metals Division symposium, Greater Than the Sum of Its Parts—Concurrent Alloy Design and Processing Science, which was held in honor of Raymond Decker’s 90th birthday. In this presentation, Decker, who has been a member of TMS for 70 years, looks back at a century of evolution in alloy design and application, from 1921 to 2021.
"Near Net Manufacturing of Light Metal Alloys"
Mark Easton
RMIT University
About the Presentation
In this talk, which was delivered at the TMS Light Metals Division Awards Ceremony & Special Lecture at TMS2021 Virtual, Easton discussed challenges to the processes of near net shape manufacturing and how some of the themes of this research can travel from one manufacturing technology to the next.
Materials Processing & Manufacturing Division
"The High Entropy Alloy Space Is Not as Big as We Think It Is"
Presenter: Raymundo Arroyave, Texas A&M University
Co-Author: Tanner Kirk, Texas A&M University
About the Presentation
How big is the available feasible alloy space in high-entropy alloys (HEAs)? That is the question this invited talk from the Computational Thermodynamics and Kinetics Symposium at TMS2021 Virtual sets out to answer.
"Applying Additive Manufacturing Itself as a High-throughput Tool to Accelerate Heat Treatment Design of Additively Manufactured Alloys"
Presenter: Wei Xiong, University of Pittsburgh
Co-Authors: Yunhao Zhao, Noah Sargent, and Kun Li, University of Pittsburgh
About the Presentation
In this invited talk from the symposium Additive Manufacturing: Solid-State Phase Transformations and Microstructural Evolution, Xiong discusses research done by his group, which developed a gradient temperature heat treatment on a bar shape Inconel 718 alloy sample prepared by the laser powder bed fusion.
Structural Materials Division
"Beyond Superalloys: An Efficient Strategy for Assessing Environmental Resistance"
Bruce Pint
Oak Ridge National Laboratory
About the Presentation
As part of the symposium Materials for High Temperature Applications: Next Generation Superalloys and Beyond, Pint’s talk looks at the interest in developing new materials with higher temperature capabilities to improve cycle efficiency and thereby reduce fuel consumption and greenhouse gas emissions.
"The Role of Fracture in the Reduction of Iron Ore with Hydrogen"
Dierk Raabe
Max-Planck Institute
About the Presentation
In this invited presentation, delivered as part of 100 Years and Still Cracking: A Griffith Fracture Symposium at TMS2021 Virtual, Raabe poses the question: Can the global market for metallic products be turned into a circular/sustainable one?
