Semisolid metal processing (SSMP) is a technology that involves the formation of metal alloys between solidus and liquidus temperatures. For the step to operate successfully, the microstructure of the starting material consist of solid near-globular grains surrounded by a liquid matrix and a wide solidus-to-liquidus transition area. Thus the process of SSMP relies on the thixotropic behavior of alloys with a spheroidal rather than a dendritic microstructure in semisolid state. Now, this process is industrially successful, generating a variety of products with high quality parts in many industrial sectors. This technology promises advantages over conventional metal forming technologies. Aluminum alloys are among the most prominent and well-known materials used in the mechanical construction and automotive industries. In this investigation, effect of pouring temperature and the type of the materials poured was studied. Molten A356 and AA7075 alloys with temperatures of 620 °C, 640 °C and 660 °C was poured on the surface of inclined plates then casting in the mould.
