<p>B₄C particles are an excellent reinforcement in functionally graded Al composites (FGCMs) owing to their superior characteristics compared to other widely used ceramic particles. Fabrication of AA6061-6 wt% B₄C FGCM was done through K₂TiF₆ flux-assisted centrifugal casting, resulting in a continuous radial compositional gradient of the ex-situ B₄C and in-situ Al₃Ti particles. While the concentration of both ex-situ and in-situ reinforcements declined from outer to inner periphery, the finer in-situ particles possessed a more gradual compositional gradient than a steeper gradient for the ex-situ particles. The particle-rich outer region showed 27% and 17% higher hardness and compressive yield strength, respectively, than the particle-free inner zone, stemming from the strengthening effect offered by both the reinforcing agents. The wear property improvement was substantial as the outer region presented 67% and 52% lower CoF and wear loss, respectively, at a load of 5&#xa0;N. Deformation behavior of the FGCM was characterized using unnotched and notched impact testing. During the impact loading, a higher resistance by the outer region to crack initiation without any notch enhanced the impact energy of the FGCM by 36%. The B₄C particle fracture and initial crack extension through more pronounced void formation around the in-situ Al₃Ti phases consumed a significant impact energy. However, the crack propagation energy for the outer and inner regions remained similar due to significant secondary crack formation. This work promotes the Al-B₄C FGCM, incorporating supplementary in-situ phases, for a feasible material option in many applications requiring component property gradients.</p>
