Teledyne and Caterpillar Join Metalcasting Software Project at Argonne Laboratory

Teledyne, Inc. and Caterpillar, Inc. have joined with the U.S. Dept of Energy's Argonne National Laboratory in Argonne, Illinois, to improve metalcasting methods and products.

The effort centers on COMMIX, computer software developed by Argonne that predicts temperature and flow of hot fluids, such as molten metal poured into molds.

COMMIX has the potential to reduce costs and factory rejection rates of cast metal products, such as engine blocks and aircraft components, according to Bill Sha, manager of Argonne's COMMIX project.

"COMMIX will help to advance metal casting from a trial-and-error art to a science with a sound theoretical base and growing body of solid, technical knowledge," Sha said.

The three-year program will analyze molten metal flow through complex molds with thick and thin sections.

One goal, Sha said, is to develop techniques to produce castings that need as little machining as possible to reach their finished shape. Another goal is to produce castings that have low porosity, fine grain structure and retain good blending of alloy elements. These properties will improve quality and reduce rejection rates during inspection.

COMMIX originally was developed to predict the mixing of liquid sodium used to cool advanced nuclear power plants.

With more than 200 research projects under way in basic and applied science, Argonne is the largest fedeally funded scientific laboratory in the Midwest. It is operated by the Univ of Chicago for the U.S. Dept of Energy.

Caterpillar, headquartered in Peoria, Illinois, is the world's largest manufacturer of earth-moving, construction and material handling equipment, and manufacturer of diesel and natural gas engines and turbines.

Teledyne is a high-technology, multi-product company consisting of more than 100 individual companies and 50,000 employees.
