2018 TMS Annual Meeting & Exhibition: Algorithm Development in Materials Science and Engineering : Organized by Mohsen Asle Zaeem; Mark Tschopp; Jonathan Zimmerman; Ebrahim Asadi; Mark Horstemeyer

As computational approaches to study the science and engineering of materials becomes more vital, it is critical to develop and improve techniques and algorithms that leverage ever-expanding computational resources. These algorithms can impact areas such as: data acquisition and analysis from sophisticated microscopes and other types of laboratory equipment, analysis and extraction of critical quantitative metrics from numerical simulations of materials behavior, and the ability to leverage specific computer architectures for revolutionary improvements in simulation analysis time, power, and capability. This symposium solicits abstract submissions from researchers who are developing new algorithms and/or designing new methods for performing computational research in materials science and engineering. Session topics include, but are not limited to: - Advancements that enhance modeling and simulation techniques such as density functional theory, molecular dynamics, Monte Carlo simulation, dislocation dynamics, phase-field modeling, and finite element analysis, - New techniques for simulating the complex behavior of materials at different length and time scales, - Computational methods for analyzing results from simulations of materials phenomena, and - Approaches for data mining, machine learning, high throughput databases, and extracting useful information from large data sets of numerical results.

2017 TMS Annual Meeting & Exhibition: Defects and Properties of Cast Metals: Organized by Mark Jolly; Charles Monroe; Brian Thomas; Peter Lee

This is the 2nd International Symposium on Defects and Properties in Cast Metals sponsored by the Solidification Committee of the TMS MPMD. The first was held at the 141st TMS Annual Meeting in Orlando, Florida, from March 12-15, 2012. Defects generated during the casting of liquid metals, whether during primary metal processing or shape casting, dramatically affect the subsequent mechanical and physical properties of the final product. These defects arise from a range of fundamental mechanisms such as surface oxidation, entrainment and incorporation of exogenous materials from the containment vessels, dissolved gasses, solidification shrinkage, unwanted micro-structural phases with detrimental morphologies and the development of stresses in the solidifying metal. In many instances, the generation of the defects arises from a combination of many physical processes. This symposium is seeking contributions from all alloys systems, ferrous and non-ferrous and primary, secondary or shape casting markets in order to bring together researchers in these fields who might not usually collaborate and stimulate interdisciplinary discussion. Topics include: liquid metal refining, inclusions and metal cleanliness; re-oxidation; slag / dross entrainment and fluid flow; surface defects shrinkage, gas, and porosity problems; segregation (a-, v-, freckles, inverse, centreline, etc.); hot tearing and other cracks; residual stresses, distortion, and shape problems; microstructural, precipitate- and grain defects; in-service properties, such as strength, ductility, toughness, fatigue, and wear; advanced characterization methods for defect detection, both online sampling methods and ex situ; modelling of phenomena related to defect formation; defects in casting processes such as ingot casting, DC casting, foundry/shape casting, die casting, investment casting, sand-casting, and continuous casting of steel, nonferrous metals, super-alloys, and other materials

2016 TMS Annual Meeting & Exhibition: Frontiers in Solidification: An MPMD Symposium in Honor of Michel Rappaz: Organized by Wilfried Kurz; Jon Dantzig; Alain Karma; Jeffrey Hoyt

This symposium follows the now well established symposium series “Frontiers in Solidification”. It is intended to present latest results of modeling of solidification microstructures such as solid liquid interfaces and their anisotropies, nucleation phenomena, morphological instabilities, dendrites, eutectics, peritectics, fluid flow effects, segregation and defects. The main objective of this symposium is to present research results from the interface between phenomena at different length scales (atomistic, microscopic, macroscopic), and from theoretical physics to industrial solutions, all using various theoretical approaches. In order to verify the results of the models, quantitative experiments are essential and will represent an important part of the presentations. Symposium mostly by invitation, poster presentations welcome.

2016 TMS Annual Meeting & Exhibition: Materials Research in Reduced Gravity: Organized by Douglas Matson; Hani Henein; Robert Hyers; Ivan Egry

The absence of gravitational effects such as thermal and solutal buoyancy enables investigation of a large range of different phenomena in materials science. These reduced-gravity experiments can isolate phenomena otherwise obscured in ground-based experiments leading to new discoveries that can improve materials and processes here on Earth. Long-term experiments in microgravity have a long history – from the early days of spaceflight to current experiments on the International Space Station. Ground-based facilities for reduced gravity experiment include drop tubes and towers that provide seconds of reduced gravity, aircraft that provide tens of seconds, and suborbital rockets that provide hundreds of seconds. Abstracts are solicited in all areas of materials research employing reduced gravity, including crystal growth, containerless processing, materials processing and properties, and experimental facilities for materials research.

2016 TMS Annual Meeting & Exhibition: Shape Casting: 6th International Symposium: Organized by Murat Tiryakioglu; Glenn Byczynski; Mark Jolly

Significant progress has been made in the quality and reliability of shape castings in the past several decades through a better understanding of the nature of structural defects, how they form, and how to avoid them. Light alloy castings are now replacing complex assemblies by offering weight savings and significant reduction in tooling, assembly, and quality costs. These advances have been made possible by research on the physics behind simulation codes, the quality of molten metal, the hydraulics of mold filling, and the nature of bifilms and their effect on mechanical properties. The 1st Shape Casting Symposium held in 2005 initiated a forum where researchers and foundry engineers could exchange their latest findings to improve the quality and reliability of shape castings. Since then four other Shape Casting Symposia followed this trend. In the 6th International Symposium, leading edge technologies and the latest innovations in casting process design and quality improvements relative to shape casting will be explored through presentations by researchers from around the world. Specifically - structure-property-performance relationships in cast metals - innovation in shape casting technology - modeling of shape casting processes - mechanical behavior of cast metals - quality and reliability improvement in shape castings
