| Popis: | Al-TiO2-Gr composites containing different weight percentages of TiO2 and graphite (Gr) particles were produced by stir casting method. The samples were prepared by adding TiO2 and Gr particles to the molten aluminum, then the resulting slurry was stirred at a specified temperature for a predetermined time. SEM and EDAX analyses were carried out for the as cast samples. The effects of the addition of reinforcement content on mechanical properties and workability behavior of the composites were investigated. Microstructural investigation of the final products proved that synthesized composites with well-distributed reinforcing particles could be fabricated by stir casting method. Tensile fracture analyses of the composites were conducted using SEM. The results show that the tensile strength of the composites increased with increasing weight fraction of TiO2 and Gr particles. Workability studies show that, the addition of reinforcements increases the true axial stress (σz), true hoop stress (σθ), t... |
