One of the newest technologies of grain refining is semi-solid metal process that noted in different industrials. In cooling slope casting method indicated of semi-solid method has been used in order of microstructure refining and spheroidizing by pouring molten on cooling slope. Some parameters such as cooling slop characteristics die temperature and next heat treatment on microstructure and mechanical properties of produced work piece effect on this method. In this present the effect of die temperature and heat treatment have been investigated on microstructure and A360 aluminum alloy hardness. After sample providing the sample with suitable cooling slop characteristics, investigations recognized that sample has suitable condition by 300°C die temperature. Then some samples with suitable condition reheated in 580°C for 5,10 and 15 min, then immediately quenched in 25°C water. Results indicate that the sample in 580°C has better properties in order of size, and grain shape, by the way that in this condition, the amount of hardness increase of 80.6 HB to 87.1HB, because of optimizing eutectic phases from the point of shape, size and monotonous dispense.
