Abstract:
Aluminum alloys have been widely utilized in engine pistons of automotive industries. Under such loading conditions, thermal stresses were applied to the piston material, due to the combustion process. Knowing the thermal behavior and microstructural properties of the material has an important rule for designers. Besides, the used material should withstand these thermal expansions and one way to increase this thermal strength is to add nano-particles for reinforcing the material. In the present article, the thermal behavior of piston aluminum alloys has been analyzed. This objective has been performed by thermal dilatometric measuring to find the thermal expansion coefficient. Then, the effect of adding nano-particles for reinforcing the aluminum alloy has been also investigated. In addition, the distribution of nano-particles in the aluminum matrix was also studied by the field emission scanning electron microscopy (FE-SEM). Besides, the microstructure of the piston aluminum alloy, with and without SiO2 nano-particles, was investigated.
