The influence of stirring speeds of 1000 and 1500 r/min 10mm male quartz banger 45 degree on the microstructure of Al18SiCuMg alloy was investigated.The smaller size of Si particles of rheocast sample obtained by higher cooling rate and higher stirring speed was achieved.According to the results of cavitation test, the cavitation rate of the rheocast sample opi the color that keeps on giving produced by 1500 r/min is lower than that of the rheocast sample obtained by 1000 r/min.

The different results show that the mass loss as a function of time can be approximated either by liner or quadratic equations.
