Forming of Magnesium Alloys

National Laboratory: 
Oak Ridge National Laboratory
Processing/Manufacturing Class: 
Shaping and forming
Thermo-mechanical processing
Description: 

Oak Ridge National Laboratory has a unique asymmetric rolling mill, equipped with warm rolls (up to 350°C) capable of shear rolling magnesium, aluminum, and steel sheet. Shear rolling can be used to modify the basal texture of magnesium alloys, improving room-temperature formability. Aluminum, magnesium (AZ31B, ZEK100), and Fe-Si alloys have been successfully rolled using ORNL’s shear rolling mill. ORNL also has facilities to perform dome testing at warm temperatures (up to 250°C) to evaluate the formability of magnesium alloys.

Capability Bounds: 

Maximum feedstock thickness is limited to 6 mm.

Unique Aspects: 

ORNL’s shear rolling capability is the sole one-of-a-kind system of its type available in the world.

Availability: 

The capability is available through collaborative efforts with ORNL.
