In this study, the effects of pouring temperature and pressure on structure and mechanical properties of Al - 10% Si alloys produced by green sand mold traditional gravity casting and counter gravity casting methods were investigated. The specimens were poured at 600, 640 and 690°C temperature under 100, 200, 250, 300 and 500 mmHg vacuum level. The results showed that improved mechanical properties were obtained by counter gravity casting process.
