4. Conclusions
- The microstructure of Al-SiC nanocomposites showed the existence of discontinuous Mg17Al12 phases and a uniform distribution of SiC nanoparticles that affect the mechanical properties of nanocomposites.
- The hardness and YS strengths were enhanced with the increase in SiC nanoparticle content. The maximum obtained values were 51.37 HV and 109.07 MPa, respectively, which were attained for the AZ31-1SiC nanocomposite. The enhancement of the hardness and YS was attributed to the joint contribution of the CTE, elastic modulus, and the Orowan and load-transfer strengthening mechanisms.
- Wear tests revealed a decrease in weight loss with an increase in SiC content in AZ31-SiC nanocomposites. This behavior was also confirmed by 3D images of the worn surface. The fabricated nanocomposites showed wear behavior that was inversely proportional to the hardness, which was attributed to the abrasion wear mechanism.
