    Flow-Induced Concentric Ring Distribution of WC Particles in Indirectly Extruded Al 1050 Matrix Composites

    This study reports the fabrication of Al 1050/WC composites (2 and 4 wt.% WC) using a novel ingot-stacked, disc-consolidated approach via indirect extrusion. The results revealed that indirect extrusion transformed the initial flat, WC-coated disc interfaces into a geometrically ordered concentric ring distribution across the composite cross-section. This architecture exhibited local variable thickness and angular discontinuities due to non-uniform material flow. X-ray diffraction confirmed interfacial stability at 485 °C and detected only the Al and WC phases. X-ray computed tomography quantified an overall porosity of 2.04 vol.%, characterized by irregularly shaped pores resulting from incomplete solid-state consolidation. Higher cross-sectional microhardness values were obtained at 47.8 ± 3.6 HV (2 wt.% WC) and 49.75 ± 5.6 HV (4 wt.% WC). Uniaxial tensile tests yielded ultimate tensile strengths of 81.05 ± 3.43 MPa (2 wt.% WC) and 89.45 ± 2.85 MPa (4 wt.% WC), which exceed the value reported for annealed Al 1050 by 62% and 79%. This flow-induced formation of a concentric reinforcement architecture through disc stacking and indirect extrusion provides a novel processing route, extending solid-state functional gradient material processing to single-step thermomechanical consolidation.
