| Abstract Scope |
Al-Si alloy reinforced with TiB2 particles (2, 5 and 7 wt.%) were synthesized successfully using stir casting method. K2TiF6 and KBF4 salts were used to obtain in-situ TiB2 phase in molten matrix. These in-situ composites have shown significant improvement in their mechanical properties such as yield strength, young’s modulus and micro hardness as compared to the base alloy (Al-12%Si). X-ray diffraction patterns of the obtained metal matrix composites confirms the formation of TiB2 particles. The microstructures were studied using field emission scanning electron microscopy. The in-situ formed TiB2 particles were found uniformly distributed with good interfacial bonding. Reinforcement particles were predominantly in cubical, spherical and hexagonal shapes. Fracture surface of composites contained fine dimples and some microcracks were generated and propagated through cleavage or facets zones. |
