title = {From Process to Properties: Understanding Texture and Mechanical Behavior in AM50 rods Processed by Constrained Friction Processing},
year = {2025},
note = {Constrained friction processing (CFP) is a new thermo-mechanical
technique to produce rods from lightweight metals, like Mg or Al
alloys, involving the extrusion of the material under high shear
conditions induced by the rotation of the tools. This work aims to
introduce CFP as an effective technique for producing AM50 rods. The
results show an exceptional grain refinement by a factor of 100
relative to the base material. Furthermore, the material flow formed
during the process lead to the formation of a texture gradient
ultrastrong in terms of intensity, characterized by the B-fiber
texture at the center of the rod, which is increasingly tilted outward
as the position approaches the edge. As a result, texture-dependent
deformation mechanisms are activated, resulting in particular local
mechanical properties along the rod. While all samples show
significant improvements in ultimate tensile strength, notable
enhancements in yield strength and ductility occur at the middle and
center, with an exceptional increase in elongation at break observed
at the outer portion of the rod. The study demonstrates that texture
tailoring can be achieved by controlling material flow during CFP,
enabling an optimized balance between strength and ductility for
specific applications. Furthermore, the enhanced properties indicate
that this approach could pave the way for biomedical applications when
combined with biocompatible Mg-based alloys, opening new avenues for
material development.},
