In this study, the effect of angle and length of copper made slope plate on the microstructure of A360-Aluminum alloy is investigated. Microstructure study of metallographic samples in different conditions revealed that for 400mm slope length and 60° slope angle the optimum sphierized and homogenized microstructure is achieved. | Nội dung Text Effect of angle length and circulation cooling system on microstructure A360 Aluminum alloy in semi-solid metal forming by cooling slope method Engineering Solid Mechanics 2017 9-14 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Effect of angle length and circulation cooling system on microstructure A360 Aluminum alloy in semi-solid metal forming by cooling slope method Mohammad Mahdi Kaykhaa a Department of Mechanical Engineering Faculty of Engineering University of Zabol Zabol Iran A R T I C L EI N F O ABSTRACT Article history Application of cooling slope in casting is a relatively simple process with low equipment and Received 6 July 2016 processing costs which is able to produce semi-solid slurries with different parameters such Accepted 30 October 2016 as pouring temperature length and angle of slope plate and plate type. In this study the effect Available online of angle and length of copper made slope plate on the microstructure of A360-Aluminum alloy 31 October 2016 Keywords is investigated. Microstructure study of metallographic samples in different conditions Semi-Solid forming revealed that for 400mm slope length and 60 slope angle the optimum sphierized and Cooling slope method homogenized microstructure is achieved. Also under these conditions the most hardness A360 77HB was obtained which might be because of suitable solidification conditions namely Microstructure time and rate of shear stress. After finding the suitable conditions of slope length and angle Circulation cooling system the effect of the circulation cooling system was examined and the method with cooling system was found to result in more homogenized microstructure compared to ordinary method. 2017 Growing Science Ltd.
