Abstract

Titanium is common in recycled aluminium alloys but limited in high-strength variants containing Zr and Cr. This study shows that Ti increases the liquidus temperature and promotes the formation of Al₃Ti-(Al,Si)₃(Ti,Zr) core–shell intermetallics. Zr and Si absorption reduces hardness and enhances the plasticity of Al₃Ti intermetallic. Ti addition improved extruded profile bending performance due to a reduced peripheral coarse grain depth, while cracks propagated via voids at Fe-intermetallics rather than Ti-intermetallics.

期刊介绍： Materials Letters has an open access mirror journal Materials Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Materials Letters is dedicated to publishing novel, cutting edge reports of broad interest to the materials community. The journal provides a forum for materials scientists and engineers, physicists, and chemists to rapidly communicate on the most important topics in the field of materials. Contributions include, but are not limited to, a variety of topics such as: • Materials - Metals and alloys, amorphous solids, ceramics, composites, polymers, semiconductors • Applications - Structural, opto-electronic, magnetic, medical, MEMS, sensors, smart • Characterization - Analytical, microscopy, scanning probes, nanoscopic, optical, electrical, magnetic, acoustic, spectroscopic, diffraction • Novel Materials - Micro and nanostructures (nanowires, nanotubes, nanoparticles), nanocomposites, thin films, superlattices, quantum dots. • Processing - Crystal growth, thin film processing, sol-gel processing, mechanical processing, assembly, nanocrystalline processing. • Properties - Mechanical, magnetic, optical, electrical, ferroelectric, thermal, interfacial, transport, thermodynamic • Synthesis - Quenching, solid state, solidification, solution synthesis, vapor deposition, high pressure, explosive
