Nowadays, the production of industrial components by semi-solid methods is considered as a new method. These methods are time consumable due to slurry preparation process, leading to the development of methods that allow the creation of non-dendritic structures in the shortest possible time. For example, the method of enthalpy exchange Material (EEM) is one of the most common processes that results from the proximity of two materials with high and low enthalpy. In this research, the effect of adding swarf on the structure of die casting parts has been studied on aluminum alloy A380 and the possibility of structural changes in different temperature conditions has been investigated. The microstructure of the parts has changed from dendrites to globular and the microstructure consists mainly of alpha phase, eutectic and intermetallic compounds. SEM results showed that the distribution of copper and iron elements is in grain boundaries of aluminum alpha particles. Also, the solid weight fraction was calculated using the thermal analyze results and confirmed by microscopic images.
