Semi-solid forming methods are commercially used for both cast and wrought aluminium alloys. The main advantages are elimination of runners and feeders compare to the casting methods. In addition, near-net-shape parts can be produced. Non-dendritic structures are also known to have homogeneous microstructure. One of the methods of obtaining spherical microstructure is called SIMA (Strain Induced Melt Activated). In this work; this method was applied to AA2024 alloy. In order to obtain optimum spherical structure heat treatment was carried out 590, 610, and 630 degrees C at certain time intervals. Then, moulds in the shape of a spanner with different thicknesses were used. Mould filling ability was characterized by means of microstructural analysis and using different mould temperatures. Tensile test samples were produced from the castings followed by T6 heat treatment and mechanical properties were investigated.
