Abstract
The purpose of this research is to increase the mechanical properties of 6061 aluminum alloy cast parts using nucleating agent and changing the cooling rate. In order to determine the nucleate effect, the master alloy Al-5Ti-1B was used, and two types of sand and metal molds were used to investigate the effect of cooling rate. The results of the image analysis showed that the smallest grain size with a number of 47 micrometers corresponds to the sample produced in a metal mold with the addition of germinating agent. Also, the metal sample with the addition of germinating agent had a 22% increase in hardness, a 21.5% increase in final tensile strength and a 23% increase in elongation compared to the control sample (a straight piece forged from a billet). In the continuation, in order to use the optimal method determined for the production of parts, a type of part with the geometry of the forging sample (control sample) was produced using the metal mold method with the addition of a germinating agent and in order to achieve the final dimensions and properties under the final forging operation with a low press. it placed. In this way, compared to the control sample, the production part produced by the combined method of casting and forging has a 27% increase in hardness and a 33% increase in final tensile strength, and it has the ability to replace the control sample.
