As computational methodologies in the materials science and engineering become
more mature, it is critical to develop, improve, and validate techniques and
algorithms that leverage ever-expanding computational resources. These
physical-based and data-intensive algorithms can impact areas such as: data
acquisition and analysis from sophisticated microscopes and state-of-the-art
light source facilities, analysis and extraction of quantitative metrics from
numerical simulations of materials behavior, and implementation on novel peta-
and exascale 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. Validation studies
and uncertainty quantification of computational methodologies are equally of
interest. 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, electronic-excited states, phase-field modeling, CALPHAD, and finite
element analysis;
• Advancements in semi-empirical models and machine learning algorithms for
interatomic interactions;
• 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;
• Approaches for data mining, machine learning, image processing, high
throughput databases, high throughput experiments, and extracting useful
insights from large data sets of numerical and experimental results;
• Approaches for improving performance and/or scalability, particularly on new
and emerging hardware (e.g. GPUs), and other high-performance computing (HPC)
efforts; and
• Uncertainty quantification, model comparisons and validation studies related
to novel algorithms and/or methods in computational material science.
Defects generated during the solidification of liquid metals, whether during
primary metal processing, shape casting or additive manufacturing, 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 of exogenous materials, dissolved gasses, solidification
shrinkage, unwanted micro-structural phases with detrimental morphologies and
the development of stresses in the solidifying metal resulting in hot tearing
and cracking. In many instances, defects arise from a combination of many
physical processes.
This symposium seeks contributions from all alloys systems, including ferrous,
non-ferrous, superalloys, and other materials; and from all metals processes,
including: ingot casting, DC casting, foundry/shape casting, die casting,
investment casting, sand casting, continuous casting, and advanced
solidification processes, such as additive manufacturing involving molten metal.
Topics include measurements and modeling of any phenomena related to casting
defects and properties: liquid metal refining, inclusions and metal
cleanliness; re-oxidation; slag / dross entrainment and fluid flow effects;
surface defects, shrinkage, gas, and porosity problems; segregation (a-, v-,
freckles, inverse, centerline, etc.); hot tearing and other cracks; residual
stresses, distortion, and shape problems; microstructural, precipitate- and
grain defects in the present of or without external fields, e.g. ultrasound,
electromagnetic, shearing, etc; in-service properties, such as strength,
ductility, toughness, fatigue, and wear; advanced characterization methods for
defect detection, both online and ex situ sampling methods and modeling. The
objective is to bring together researchers working in diverse fields that may
share common fundamentals and goals, but may not usually collaborate, in order
to stimulate interdisciplinary discussion. This is the 4th International
Symposium on Defects and Properties in Cast Metals sponsored by the
Solidification Committee of the TMS MPMD.
Additive manufacturing is a disruptive technology, offering increased part
complexity, short lead times, and opportunities for local microstructure
control. Microstructure and defect development in AM processes is influenced by
solidification and melt pool dynamics, but currently the application of
fundamental solidification theories to AM process conditions has not been fully
explored. Furthermore, increased demand for customized material properties and
localized microstructure control will inevitably require a detailed
understanding of solidification in these processes. The goal of this symposium
is to highlight research in metal additive manufacturing that applies
fundamental solidification theory to understand and solve contemporary
processing challenges. This symposium will inform the solidification community
about the unique characteristics of AM and guide the AM community to recognize
the parallels that exist in the welding and solidification literature. Both
experimental and modeling submissions are encouraged, especially in which
modeling or theory is connected to experimental results or in situ
characterization, as well as the use of data analytics and machine learning
approaches to building process-structure-property relationships. The symposium
will consist of 4 total sessions.

The eighth “Frontiers in Solidification" symposium will provide a forum to
present and discuss the latest advances in the field of Solidification Science.
The main focus will be on the fundamental aspects of solidification, with the
aim of advancing our understanding of how microstructures develop and evolve
during solidification experiments or processes. Beyond solidification,
contributions that investigate melting phenomena are also encouraged. The
widest range of investigation methods are considered, including theory,
experiments, characterization, modeling across all relevant length and time
scales, as well as data-driven approaches. Contributions will put forward
original interpretations, observations of novel phenomena, and/or outstanding
challenges from both fundamental and applied perspectives, as well as transfer
of fundamental knowledge to practical applications. Contributions that combine
novel characterization techniques, challenging property measurements, and
computational simulations across scales are especially encouraged.
Topics of interest include:
• Nucleation
• Growth
• Melting
• Interfaces and boundaries (solid-liquid, solid-solid, stability,
anisotropy, kinetics,...)
• Pattern formation (cellular, dendritic, eutectic, peritectic,...)
• Fluid flow and gravity effect on microstructure formation and evolution
• Segregation and defects
• In-situ and time-resolved imaging of microstructures
• Theory and modeling across all relevant length scales
• Emerging processing techniques (e.g. additive manufacturing)
• Data-driven methods in solidification science

This international symposium will be held to celebrate the 80th birthday of
Prof. John Campbell, to celebrate his life-long contributions to the
understanding of metal castings, his vision and his friendship. This will be
the 7th Shape Casting symposium, which has been a well-attended event that
produced a proceedings each time. As in the past, papers will be invited in
the following topics:
- liquid metal quality and solidification of castings
- structure-property relationships in metal castings
- Properties (tensile, fatigue, etc.) of castings
- Innovations in metal casting production technologies
The major theme in Prof. David StJohn’s career was the study of phase
transformations, particularly solidification phenomena. Of particular focus
was light metal alloys: Al alloys, Mg alloys and more recently Ti alloys. His
most recognized and awarded contribution has been in nucleation and grain
refinement, but he has made contributions to a wide range of solidification
problems including defect formation, melt treatment and casting alloy design.
To cover the main themes of his research career the following session topics
are suggested: Nucleation and Grain Refinement of Light Alloys; Eutectic and
Peritectic solidification; Defect formation in castings: porosity and hot
tearing; Solidification under external fields; Magnesium Casting and Alloys;
Aluminium Casting and Alloys, Solidification during Additive Manufacturing, and
Approaches to Collaborative Research.
