| Abstract Scope |
Aluminum composites were fabricated in a novel manner to characteristically induce a layer-wise alignment of micro-scale Al3Ni and Al3Ti rectangular intermetallic particles that were formed in situ within a ductile Al matrix. The simple and unique Rolling of Randomly Orientated Layer-wise Materials (RROLM) manufacturing methodology enables microstructural tailoring of the intermetallic reinforcing particles to prescribe enhanced crack tip deflection caused by the complex interaction of local veins of reinforcement particles, in an effort to overshadow the classical loss of toughness in large-particle reinforced composites. The complimentary reinforcements and their interface with the Al matrix are revealed to have a gradual transition zone that functions to maintain critical cohesion with the particles and the matrix, empowering the superior load transfer capability of the particles and reducing microvoid penetration into the matrix. |
