Abstract: Despite the high demand for strong, lightweight, and tough Aluminum Matrix Composites (AMCs) across various applications, achieving desired property compatibility remains challenging due to limited control over the reinforcement processes. A novel AMC has been developed and synergistically reinforced with transgranular microscale Al 3 Ti, sub-microscale TiN, and intergranular nanoscale AlN, through Ti 2 AlN and Al in situ reaction. The in-situ multiphase-and-scale structure, resulting from the intricate reaction mechanisms and N interstitial solution, was analyzed using experimental investigations, thermodynamics and kinetics calculations, while the robust interfacial properties were studied by first-principles calculations. Both endowed the composite with exceptional strength (776 MPa and 635 MPa for compressive and flexural strength). Strengthen mechanisms were composed of fine-grain, solid-solution, and dislocation strengthening. This work succeeds in refining Al 3 Ti particles and creatively breaks through the bottleneck of synthesizing multi-dimensional and tunable in-situ reinforcements, expected to open new avenues for developing and applying a new generation of advanced AMCs. [Display omitted] • Advanced AMC with exceptional strength was fabricated through Ti 2 AlN and Al in situ reaction. • Transgranular microscale Al 3 Ti, sub microscale TiN, and intergranular nanoscale AlN were obtained. • Al 3 Ti coarsening was restricted. • The reaction mechanisms and the coherent transition interfaces were analyzed and calculated by DFT. • The strengthening mechanisms where the in-situ reinforcements do respective pieces were proposed.
