Article Description

Hypereutectic Al–Si alloy (A392) was treated with ultrasonic vibration (UV) induced to the melt through a cylindrical resin–bonded sand mold. This work aims at studying the influence of UV at the different pouring temperatures of A392 alloy during solidification process on the microstructures and mechanical properties. The microstructures of as-cast samples were examined by using optical microscopy (OM) and scanning electron microscopy (SEM). The mechanical properties were investigated by tensile and hardness tests. The results showed clearly that with applied UV at optimum pouring temperature (640 oC), nearly fine uniform and polyhedral shape of the primary Si were obtained. Improvement of tensile properties and hardness of the investigated alloy modified with UV is related to the modification and refinement of primary Si particles. The fracture surfaces of prepared alloy without and with UV were also investigated.
