        The use of aluminum alloys in various industries, especially the automotive industries, to have less structural weight, is on the rise. The use of semi-solid forming process in addition to changes in the microstructure which improves the mechanical properties can reduce the volume of production and ultimately lead to the improvement of the structural weight. In this paper, optimization of the governing parameters is investigated in one method of the semisolid forming named the mechanical vibration. A380 grade aluminum alloy is cast in our study. The initial parameters that investigated here are the pouring temperature, frequency and holding vibration time. The output result is investigated on the hardness. As the result showed the hardness value of 80 is the best result. Also results showed that the temperature of the melt is the important parameter in this method. Also the hardness will be increased when the frequency and holding vibration time increases تفاصيل المقالة
