Penelitian ini bertujuan untuk mengetahui mekanisme analisis kegagalan material yang dilakukan pada sayap pesawat terbang. Analisis dilakukan dalam bentuk inspeksi visual, fraktografi makro, dan fraktografi SEM. Analisis tersebut menggunakan uji komposisi dengan spektroskopi X-ray fluorescence (XRF) dan Oxford Instruments X-MET 5100, analisis makroskopik dengan kamera digital Nikon SMZ 1500 dan mikroskop stereo, dan analisis fraktografi pembesaran yang lebih tinggi dilakukan dengan menggunakan FEI XL40 SFEG SEM. Berdasarkan analisis yang dilakukan, ditemukan bahwa kegagalan terjadi pada komponen sayap pesawat, retakan intergranular karena kelemahan struktur mikro, adalah penyebab kegagalan material. Analisis kegagalan material sangat penting untuk mengetahui dan mengungkapkan penyebab dan penanggulangan komponen yang gagal. Bentuk kegagalannya bisa berupa retakan, patah tulang, korosi, dan lain-lain.

Review of Aluminum Alloy Development for Wire Arc Additive Manufacturing

Processing of aluminum alloys by wire arc additive manufacturing (WAAM) gained significant attention from industry and academia in the last decade. With the possibility to create large and relatively complex parts at low investment and operational expenses, WAAM is well-suited for implementation in a range of industries. The process nature involves fusion melting of a feedstock wire by an electric arc where metal droplets are strategically deposited in a layer-by-layer fashion to create the final shape. The inherent fusion and solidification characteristics in WAAM are governing several aspects of the final material, herein process-related defects such as porosity and cracking, microstructure, properties, and performance. Coupled to all mentioned aspects is the alloy composition, which at present is highly restricted for WAAM of aluminum but received considerable attention in later years. This review article describes common quality issues related to WAAM of aluminum, i.e., porosity, residual stresses, and cracking. Measures to combat these challenges are further outlined, with special attention to the alloy composition. The state-of-the-art of aluminum alloy selection and measures to further enhance the performance of aluminum WAAM materials are presented. Strategies for further development of new alloys are discussed, with attention on the importance of reducing crack susceptibility and grain refinement.

“…According to the principle of equal strength selection of welding materials, and because of 7xxx aluminum alloy can precipitate the second phase in a specific sequence to strengthen the α matrix [16][17][18][19], it can be seen that 7XXX aluminum alloy welding wire is very suitable for 7075 welding. Oropeza D et al used self-made titanium carbide reinforced 7075 welding wire to TIG weld 7075 aluminum alloy, and the joint strength after heat treatment could reach up to 84% of the base metal [20]. Zhang K et al used self-made 7075 wire and TIG welding to weld 5 mm thick 7075-T6 aluminum alloy, and then heat-treated the joint to obtain welding joint with the tensile strength of 424.5 MPa and elongation of 9.83% [21].…”

7075 aluminum alloy butt welding was carried out by TIG welding with self-made 7075 wire. The effects of different currents on the microstructure and mechanical properties of the joint before and after heat treatment were studied. Before heat treatment, the strength and elongation of the joint are 274.84 MPa and 6.3%, which are determined by the presence of a large number of second phase precipitates with different shapes. After heat treatment, the tensile strength and elongation are increased to 511.75 MPa and 13.76%. Since most of the second phase has been dissolved, the grain size becomes the decisive factor. The fine grain size and more sufficient recrystallization degree make the mechanical properties of the low-current joint better.
