2022 TMS Annual Meeting & Exhibition: Advanced Characterization Techniques for Quantifying and Modeling Deformation: Organized by Mariyappan Arul Kumar; Irene Beyerlein; Wolfgang Pantleon; C. Tasan; Olivia Underwood Jackson

Objective: This symposium will provide a venue for presentations featuring the use of advanced characterization techniques in all classes of materials to quantify and model deformation mechanisms. Background and Rationale: Advances in characterization technology have greatly improved our ability to quantify deformation mechanisms such as dislocations, twinning, and stress induced phase transformations, and the microstructural changes accompanying deformation such as texture evolution, grain morphology changes, and localized strain. A variety of relatively new techniques are being applied to both structural and functional materials. These techniques, in combination with modeling, are improving our understanding of deformation and failure during material processing/forming and under normal or extreme conditions in service. In situ techniques, especially, are providing enhanced understanding of individual mechanisms, their interactions, and direct validation of simulations from computational materials science models. This gathering provides a venue to discuss and share new advances in current techniques or new technique development or in pairing with algorithms or simulations as they apply to deformation behavior. Areas of interest include, but are not limited to: (1) Dislocations, deformation twins, and stress-induced phase transformations (2) All advanced X-Ray-based techniques (3) All advanced electron-based techniques including HR-(S)TEM, EBSD, HR-EBSD, ECCI, PED, in situ TEM (4) All structural and functional materials systems (5) Advances in material modeling through the use of advanced characterization techniques (7) New characterization and in-situ technique development

2022 TMS Annual Meeting & Exhibition: Furnace Tapping 2022: Organized by Joalet Steenkamp; Dean Gregurek; Quinn Reynolds; Gerardo Alvear Flores; Hugo Joubert; Phillip Mackey

Many a metallurgist fell in love with pyrometallurgy after witnessing a smelter being tapped. There is something magical in the combination of light, energy and danger that simultaneously stirs the primal instincts to ‘run for your life’ and ‘go closer and have a look’. But tapping a smelter is not an easy task. Much engineering go into the design of the tap-hole. Due to the aggressive nature of the process, material selection is as important as layout. The design process kicks off with a set of design criteria, which needs to be revised as the results of laboratory, compational fluid dynamics (CFD) and time-and-motion studies become available. The tap-hole life-cyle is taken into account with designers addressing the requirements for installation and operability as well as for maintenance. Matters such as online monitoring of the taphole wear, handling of liquid products, and extraction of fumes are all taken into account. Though tap-hole life can be improved with proper design, a good design can be destroyed with incorrect tapping practices and equipment. Despite the harshness of the tapfloor environment, it requires precision equipment and operating practices. The design and maintenance of the drilling, tapping and plugging equipment and materials plays an equally important role in tap-hole life and tapfloor safety. As does protective equipment. Operators want the tap-hole life to be as long as possible since tap-hole failures is often the cause for a reline—a very expensive exercise in an upcycle when the cost of a new lining is small compared to the loss in production. Managing the maintenance and reline schedule is a challenge with lessons often learned the hard way. The first thing students are taught in pyrometallurgy courses is how to compile a mass and energy balance for a smelter. An accounting mass and energy balance is used not only to schedule furnace taps but also to make process decisions. Process variables measured during or after tapping are important inputs to a workable mass and energy balance. Even though much has been done to make the tapping process as automatic as possible, tapping of smelters cannot be done without labour. Tap floor operators work in harsh environments where safety is of utmost importance. Selection of suitable personnel and intensive training is required. No pyrometallurgical smelter can operate without some form of tapping system. It is the one thing all smelters have in common. A meeting point of science, technology and skill. So let us talk about it.

2020 TMS Annual Meeting & Exhibition: Characterization: Structural Descriptors, Data-Intensive Techniques, and Uncertainty Quantification: Organized by Shawn Coleman; Tomoko Sano; James Hogan; Srikanth Patala; Oliver Johnson; Francesca Tavazza

This symposium focuses on the development and use of computational and data intensive characterization capabilities used by experimentalists and modelers to investigate materials structure and mechanisms at varying length and time scales. Advancements in computational processing power; instrument and detector capabilities; and multi-scale experimental and modeling techniques are generating increasingly large datasets that have facilitated the discovery of quantitative descriptors that link structure to processing parameters and material properties. For example, experimental techniques such as 3D x-ray and synchrotron tomography; atom probe tomography; multi-modal imaging; and high frame rate imaging are generating enormous characterization datasets used to understand and quantify material structure and behavior. Similarly, atomistic and mesoscale simulations are generating large datasets that provide insights for the genesis and evolution of various microstructural features, and provide links to higher order models and experiments. Throughout the materials community, scientific discoveries using these large characterization datasets are being accelerated through the advancement and automation of analysis techniques such as machine learning and artificial intelligence. As these computational and data intensive characterization approaches advance, there is a call for deeper study to quantify their inherent uncertainty of structural descriptors. This symposium intends to bring together experimental and theoretical experts in computational and data intensive microstructure characterization from both academia and industry, with a focus on the methods and techniques to effectively manipulate, reconstruct, analyze, and apply these data to develop improved predictive capabilities for multi-scale materials design. Suggested areas of focus for this symposium include: • Theoretical and computational development of novel structural descriptors to characterize microstructural features (e.g. grain boundary atomic and crystallographic structure, crystallographic texture, distributions of triple junction types), and their application to quantitatively characterize experimental and simulation data, and develop new predictive microstructure-property models. • Methods and algorithms for collecting, reconstructing, analyzing, and quantifying large experimental microstructural datasets collected from tools such as: atom probe tomography, x-ray computed tomography, or high-speed measurements. • Methods and algorithms for the detection, analysis, and quantification of microstructural features predicted through atomic and mesoscale simulation data. Validation approaches for computational and theoretical models using structural descriptors and advanced experimental mechanics techniques. Methods to bridge modeling and experiment through computed characterization (e.g. virtual X-ray and electron diffraction and simulated microscopy). • Application of advanced analysis techniques, such as machine learning and artificial intelligence, to develop multi-scale microstructure descriptors and provide greater insights into materials characterization data. • Methods for quantifying the uncertainty inherent in manipulation, reconstruction and analysis of large sets of characterization data.
