Researchers at Pacific Northwest National Laboratory have developed a unique capability to extrude powder, flake, and solid billets of novel alloys and composites. Extrusions on the order of 0.4- to 0.75-inch diameter are produced, enabling mechanical properties to be tested on samples of prototypic scale. In addition to alloy development, PNNL’s extrusion capability affords the correlation of extrusion die design and processing parameters in evaluating microstructure, properties, and production limits. This is important when trying to develop unique alloys while optimizing performance versus productivity.
PNNL maintains a 500,000-lbs. (225 metric tons), 4-post, indirect extrusion press. Billet and extrusion die temperatures up to 400°C allow for the extrusion of most aluminum and magnesium alloys.
PNNL offers unique die designs, thermal profile measurements, load cell, and cross-head displacement controls that enable thorough characterization of the extrusion process.
Facilities are available for both government and private (proprietary) project work.
