520			_aGrain refinement has many beneficial effects on Al-cast alloys, such as increasing fluidity, reducing hot cracking, reducing micro porosity, improving yield strength, and improving fracture toughness. This work was carried out to investigate the effect of pouring temperature on the grain size and morphology of Al-4.5% Mg (JIS-AC7A) and Al-7% Si (JIS-AC4C) cast alloys. In addition, the effect of ultrasonic treatment (UST) was also investigated on the same alloys
