According to non-dendritic method, there are four main techniques working in Semi-Solid state. The four techniques for preparation non-dendritic samples were Semi-Solid Rheocasting (SSR), Cooling Slope (CS), Magneto-Hydrodynamic stirring (MHD) and Semi-Solid Rheocasting with Cooling Slope (SSR+CS). In this paper, the non-dendritic feedstocks prepared depending on the aluminum alloy A201. The feedstocks have been investigated using metallographic and Vickers hardness methods. The results of the work showed main difference between the non-dendritic samples and dendritic samples focusing in microstructure and hardness techniques. Comparing the non-dendritic techniques results, The Rheocasting (SSR) mothed was high result in the microstructure and mechanical properties.
