Abstract Scope |
The Solid Phase Processing group at the Pacific Northwest National Laboratory is investigating the role of extreme deformation on the ability to extrude and join magnesium alloys. This presentation will highlight two emerging technologies currently being developed; Rotating Hammer Riveting (RHR) and Shear Assisted Processing and Extrusion (ShAPE), with examples given for their implementation of magnesium alloys. Magnesium alloy AZ31 has been joined to thermoplastic carbon fiber reinforced polymer (CFRP) by RHR. With RHR, the rivet head is mixed with, and metallurgically bonded to, the underlying sheets being joined to form a robust fastener. The RHR process, joint properties, and microstructural characterization will be discussed. Non-rare earth magnesium alloy ZK60 has been extruded by ShAPE to form thin-walled tubing with a highly refined microstructure and basal plane alignment away from the extrusion direction. These tubes have been slit and rolled into sheet and foil with anisotropic material properties. |
