Abstract
Processing of alloys in the semisolid state has several advantages over conventional casting processes, such as reduction in macrosegregation, porosity and improved mechanical properties. In this study, produced A356 alloy by means of cooling channel and strain induced melt activation (SIMA) processes has been investigated, and their microstructures and hardness were evaluated. At first, in cooling channel process, the grain size is smaller than that in the conventional cast processes and increases with increasing time. Before heat treatment, the microstructure of the SIMA sample is elongated towards the rolling side in contrast to spherical structure in the cooling channel process. The hardness value of sample in the SIMA process is greater than that in the cooling channel process without heat treatment. When the solution annealing was carried out within 2 h, the globular microstructure in both samples was observed. Finally, the grain size and the hardness of samples were determined as 150 μm and 60 HV respectively.
