Presentation Title YP-4: Increased Shear Deformation through Friction Stir Back Extrusion of Mg AZ31B: Textural Evolution and Its Relationship to Mechanical Properties

On-Site Speaker (Planned) Justin Milner
Abstract Scope Friction stir back extrusion (FSBE) has been recently introduced as a promising technique for processing of lightweight alloy tubes with unique microstructure and mechanical properties. This work focuses on quantifying the effects of processing parameters on the material’s resultant texture and exploring the potentials for enhancing its performance. AZ31B-F magnesium round bars are processed into tubes by FSBE at three process conditions, leading to three distinct tubes with varying degrees of shear deformation. Textural examination via electron backscatter diffraction and neutron diffraction is carried out at key locations throughout the processed tubes in order determine the relationship between resultant texture and mechanical properties of the processed tubes. Through varying the processing parameters of the FSBE process technique, tubes can be tailored with unique textural characteristics, which can lead to a 300% increase in elongation as compared to the base material.
