About this Symposium
Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Fundamental Aspects and Modeling Powder Metal Synthesis and Processing
Sponsorship TMS Materials Processing and Manufacturing Division
TMS: Powder Materials Committee
Organizer(s) Paul Prichard, Kennametal
Eugene Olevsky, San Diego State University
Iver Anderson, Ames Laboratory
Scope This symposium joins the communities interested in fundamental aspects of powder metallurgy, both modeling and experimental.
It represents the TMS Powder Materials Committee initiative to bring together the individuals specializing in basic research on powder synthesis and consolidation fulfilling the goals of TMS annual conferences of creating an interdisciplinary and fruitful research environment.
The related modeling application topics include conventional and field assisted powder consolidation processes (powder compaction, pressureless sintering, spark-plasma and microwave sintering, hot isostatic pressing, and novel consolidation techniques), nano-sintering, grain growth, interface effects, in-situ measuring techniques at various scale levels, modeling of die filling and powder spreading, modeling of sintering phenomena in additive manufacturing, simulation of powder synthesis.
The modeling techniques (including physics based, phenomenological, and empirical) or fundamental experimentation are expected to cover multiple scale levels, starting from atomistic dimensions up to the scale of real world macroscopic components.
Considering the high level of interest of research and industrial communities in these topics, we expect about 50-80 abstracts in this combined event, with an attendance of 50 people per section.

Potential session topics are:

- Modeling of powder compaction under ambient and elevated temperatures
- Fundamental aspects of conventional, microwave, spark-plasma and flash sintering
- Grain boundary and interface energy effects on sintering & grain growth
- Modeling of die filling and powder spreading
- Modeling of sintering phenomena in additive manufacturing
- Modeling and fundamental experimentation on powder synthesis
- Consolidation of multi-layered materials
- Fundamental aspects of fabrication of powder-based electronic and bio-materials
- In-Situ Measurements of powder synthesis and consolidation
