ORNL has a unique asymmetric rolling mill, equipped with warm rolls (up to 300°C) capable of shear rolling magnesium, aluminum, and steel sheet. Shear rolling can be used to modify the basal texture of magnesium alloys, thus improving room temperature formability. Aluminum alloys, magnesium alloys (AZ31B, ZEK100), and Fe-Si alloys have been successfully rolled using this unique shear rolling mill. ORNL also has facilities to perform dome testing at warm temperatures (up to 250°C) to evaluate magnesium alloy formability.
Maximum feedstock thickness is limited to 6 mm.
The shear rolling capability is the sole one-of-a-kind system available in the world.
The facility is available through collaborative efforts with ORNL.
