Honorary Symposia

Solidification Processing of Light Metals and Alloys: An MPMD Symposium in Honor of David St John

Date: Monday, March 11, to Wednesday, March 13, 2019 
Location: Henry B. González Convention Center, Room 006C

The major theme in Professor David St John’s career was the study of phase transformations, particularly solidification phenomena. Of particular focus was light metal alloys: aluminum alloys, magnesium alloys and, more recently, titanium 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.

• 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
• Approaches to collaborative research

Grandfield, Grandfield Technology Pty Ltd, Australia; Norbert Hort, Helmholtz-Zentrum Geesthacht, Germany; Mark Roderic Jolly, Cranfield University, United Kingdom

Interfaces in Structural Materials: An MPMD Symposium in Honor of Stephen M. Foiles

Date: Monday, March 11, to Thursday, March 14
Location: Henry B. González Convention Center, Room 302C

The key to the development of advanced materials with tailored microstructures and architectures is a detailed understanding of interfaces. In particular, the significance of internal (grain and phase) boundaries as well as free surfaces becomes more dominant in applications where a reduction of system size or scale of microstructure is desired to optimize properties. It is to this field that Dr. Stephen M. Foiles made significant contributions over a period of over 35 years. The goal of this symposium is to bring together researchers across a wide range of disciplines to communicate recent advancements pertaining to the study of materials interfaces (free surfaces, solid-liquid, grain boundaries) both computationally and experimentally. The contributions of Foiles to the development of interatomic potentials for atomistic simulations and study of materials interfaces will be highlighted.

• Interatomic potential development and its use to model materials behavior
• Thermodynamics of interfaces
• Dynamical behavior of interfaces (crystal surfaces, grain boundaries (GB), phase boundaries, solid-liquid)
• Phase transitions and microstructural evolution
• Interface properties (energy, mobility, etc.)
• Interface segregation/adsorption
• Interface-defect (dislocation/vacancy) interactions (radiation, mechanical, etc.)

Green Materials Engineering: An EPD Symposium in Honor of Sergio Monteiro

Dates: Monday, March 11, to Wednesday, March 13 
Location: Henry B. González Convention Center, Room 008A

The main focus of this symposium is green materials, comprising: natural composites, bio-inspired armors, waste added clay ceramics, lignocellulosic fibers, and biodegradable polymers. Also part of the technical scope of this symposium is any type of natural material that could be related to engineering applications. This TMS Extraction & Processing Division (EPD) symposium will be held in honor of Sergio Monteiro, professor at the Military Institute of Engineering, IME, Brazil.

SYMPOSIUM ORGANIZERS: Shadia Jamil Ikhmayies, Isra University, Jordan; Jian Li, CanmetMATERIALS, Canada; Carlos Mauricio Vieira, State University of the North Fluminense, Brazil; Jean Margem*, State University of the North Fluminense, Brazil; Fabio Braga, Military Institute of Engineering, Brazil
