Microstructural, Mechanical, and Fracture Characterization of Metal Matrix Composite Manufactured by Accumulative Roll Bonding

Accumulative roll bonding is a severe plastic-forming process proposed to manufacture ceramic particle-reinforced multilayered metal matrix composites. In this work, low-cost composite laminate was produced by commercially pure aluminum 1100 with 5% in volume of reinforcing microscale silicon carbide particles. Microstructural features, hardness, tensile properties the presence stress concentrators, and wear resistance were assessed. Fracture surface inspection carried out determine operating failure mechanisms. Hardness significantly enhanced, whereas only moderately improved particles incorporation. The main reasons some degree recrystallization, work-hardening relief due periodic annealing, minimum grain refinement, somewhat agglomerated Though increments not much attractive, exceptional increase performance achieved addition particulate carbon-rich phase, which acted as solid lubricant mitigating abrasion, adhesion, delamination manufactured can be worthwhile applications where low cost, notch insensitivity, superior weather resistances are design requirements, outdoor decks patios.
