IIT's Main Campus
The objectives of this workshop are to establish the state-of-the-art
in heat treat process modeling and simulation, to determine the needs of
industry, and to define a clear vision of how to meet the challenges required
to move the technology forward (a technology roadmap) to satisfy those needs.
The outcomes will be:
1)
A technology roadmap document which will be circulated to all participants
after the meeting
2)
Networking
3)
For industry participants, an increased awareness of the capabilities and
limitations of current simulation tools
4)
For academics and software developers, an understanding of the needs of
industry
5)
CD of all presentations and proceedings of the workshop
6)
Formation of collaborative research teams
Description of Workshop
The workshop will consist of presentations by invited speakers from industry,
academia and national laboratories, a poster session, software demonstration
sessions and some focused discussion groups.
The presentations will cover the following topics:
-
The state of the art in heat treat process simulation
-
The needs of industry
-
Validation methodologies and benchmarking
-
Materials properties database needs
-
Challenges in microstructural
modelling and properties prediction
The focused discussion groups will cover topics including mechanics,
processes, heat transfer, thermodynamics and kinetics of phase transformations,
and properties databases. A final discussion period for the whole group
will serve to develop a consensus on a technology roadmap. This will consist
of the needs of industry, topical areas and focused research projects within
those areas that are needed to improve the prediction and simulation capabilities
of the technology, planned mechanisms to assist transfer of the technology
to industry and a strategy to implement the road map (sources of funding,
collaborative research teams).
The workshop will focus mainly on heat treating processes, but will also
include hot deformation processing since the software developed can, and
should, be integrated. The workshop will not include solidification processes
in the presentations unless they specifically deal with microstructure evolution
of significance to the heat treating processes.
However we do expect poster presentations and software demonstrations
in solidification.

6. Modeling Needs for Hot Metal Gas Forming
Richard Fields, NIST
Abstract
Hot Metal Gas Forming is a new process that is intended to provide
tubular frame structures for the auto and aircraft industry. The equipment is
considerably less expensive than that currently used in hydroforming, yet the
thermal processing provides an additional variable that can be used to great
material advantage. This presentation will describe the process, identify the
difficulties, and try to define the modeling needs to accelerate the
successful
HMGF of aluminum and steel.
7. A Critical Review of FEM-Based Modeling of Heat Treatment
Processes
Calvin Tszeng
IIT
Abstract
Reliable computational methods for predicting the microstructure,
properties and distortion of heat treated components have been one of
the most critical needs in the heat treating industry. This talk presents
a critical review on the current capability and limitations of FEM (finite
element method) based modeling for predicting the thermal-mechanical and
metallurgical evolution in heat treating processes. The issues to be addressed
include: thermal boundary conditions; kinetics models and associated data
of phase transformation; and the constitutive models and material data
of multiphase materials. This presentation also includes discussion on
the research being conducted in the Thermal Processing Technology Center
at Illinois Institute of Technology.
8. SYSWELD Heat Treatment Advisor: Process Simulation Software for
Manufacturing
Bruce Rodewald
ESI North America
Abstract
With improvements in speed of workstation computers and PCs, the
ability for full manufacturing process validation is being realized in simulation.
ESI's SYSWELD Heat Treatment Advisor employees the power of the
long-standing SYSWELD product capability to attack a multitude of heat
treatment problems, with ease of use and high accuracy. The implementation
of this software in Europe, Asia, and now the United States has drastically
changes the way process prototyping is conducted for OEM Manufacturers
and their suppliers.
