Pengaruh volume Zn terhadap kekerasan dan struktur mikro pada friction stir processing aluminium AA 1100

Friction Stir Processing (FSP) merupakan salah satu proses pengerasan permukaan logam ringan seperti aluminium yang dikembangkan berdasarkan prinsip kerja FSW. Penggunaan aluminium dan paduannya sebagai komponen permesinan semakin banyak digunakan. Hal tersebut dikarenakan aluminium dan paduannya memiliki sifat yang ringan dan mampu bentuk yang baik. Kajian ini bertujuan untuk mengetahui pengaruh volume Zn terhadap sifat mekanik dan fisik material aluminium alloy 1100. Sifat mekanik dianalisa melalui pengujian kekerasan vickers, sedangkan sifat fisik diamati melalui pengamatan struktur makro, mikro, dan SEM. Variasi yang diguinakan yaitu volume Zn 22 mm3, 45 mm3, 67 mm3, 90 mm3, dan tanpa penambahan Zn. Kecepatan putar tool, dwell time, dan plunge depth dalam keadaan seragam. Hasil pengamatan SEM dan mapping menunjukkan persebaran Zn yang tidak merata pada SAZ. Hal ini dibuktikan dengan kandungan Zn yang tinggi pada daerah tepi tool pada pengamatan EDS. Hasil pengujian kekerasan menunjukkan semakin meningkat seiring bertambahnya volume Zn. Nilai kekerasan permukaan FSP AA1100 tertinggi yaitu 87,5 HV dengan variasi volume Zn terbanyak, sedangkan dengan variasi tanpa penambahan Zn sebesar 44,7 HV.

AbstractMechanical alloying can be carried out by a method known as friction stir processing, whereby solid Zn particles in a solution are distributed onto an aluminium alloy plate. The aim of this study was to determine the effects of a volume of Zn particles on the mechanical and physical properties of aluminium 1xxx alloy that had been subjected to friction stir processing. The specimens were plates composed of 1xxx series aluminium. A groove, measuring 12 mm in diameter, was pierced to various depths, and the Zn particles in these containers were then subjected to friction stir processing using a pin-less tool with a diameter of 15 mm. The results showed that the highest hardness was found in the uppermost layer of the workpiece, and this gradually decreased with thickness. An increase in the amount of Zn particles caused an increase in material hardness. The highest hardness of 87.1 HV in the friction stir-processed AA1100 was obtained at the highest volume of Zn compared to the hardness of 44.5 HV, which was obtained for the specimen without the addition of Zn.

This paper presents the analysis of the friction stir-processed aluminium alloy 5083-H111 gas tungsten arc-welded and friction stir-welded joints. The comparative analysis was performed on the processed and unprocessed gas tungsten arc-welded and friction stir-welded joints of similar aluminium alloy 5083-H111. The results showed a clear distinction between the friction stir processed joints and unprocessed joints. There is a good correlation observed between the microstructural results and the tensile results. Ultrafine grain sizes of 4.62 μm and 7.177 μm were observed on the microstructure of the friction stir-processed friction stir-welded and gas tungsten arc-welded joints. The ultimate tensile strength for friction stir-welded and gas tungsten arc-welded before friction stir processing was 153.75 and 262.083 MPa, respectively. The ultimate tensile strength for friction stir processed friction stir-welded joint was 303.153 MPa and gas tungsten arc-welded joints one was 249.917 MPa. The microhardness values for the unprocessed friction stir-welded and gas tungsten arc-welded joints were both approximately 87 HV, while those of the friction stir-processed ones were 86.5 and 86 HV, respectively. The application of friction stir processing transformed the gas tungsten arc morphology from brittle to ductile dimples and reduced the ductile dimple size of the unprocessed friction stir-welded joints from the range of 4.90–38.33 μm to 3.35–15.59 μm.
