[[alternative]]The Study of Mechanical properties on The Post Weld Treatment of Aluminum Alloy 5052 and 6061
No full text[[abstract]]Because the characteristics of low weight, easy formability, good corrosion and oxidation resistance, aluminum alloy have been applied extensively in engineering structures and general appliances. Because the increase ing use in the industry, it is very important to study the weldability of dissimiliar joing of aluminum alloys.
The purpose of this research was to systematically study the weldability of aluminum alloys under Tungsten Inert Gas Arc Welding (TIG). The base metals used were 5052-H32 and 6061-T6 with filler metal of ER5356. Different post weld heat treatments of the 5052 and 6061 weldments were conducted. A series of experiments including tensile testing, microhardness testing, optical metallography and SEM analysis were used to determine the releationship between mechanical properties and microstructures of the alumimum weldments.
The experimental results indicate that there is no obvious difference on the 5052-H32 weldments because they are non-heat-treatable aluminum alloys. Proper post weld heat treatment (160℃, 8 hours) can increase the mechanical properties of the 5052-6061 weldments. Post weld full heat treatment has a great influence on mechanical properties of the HAZ of 6061-T6 weldment.
[[alternative]]THE STUDY OF MECHANICAL PROPERTIES ON THE PRE-WELD AND POST-WELD COLD WORKING OF ALUMINUM ALLOYS 5052
No full text[[abstract]]Because the characteristics of ‘high strength to weight’ ratio, easy formability and good corrosion resistance, aluminum and its alloys have been applied extensively in industry. Some problems obtained from welding process can heavily influence the mechanic properties of aluminum alloy weldment. The problems can be eliminated only by proper welding skills and cold working.
The purpose of this research is to study the ability of weld in aluminum alloys weldments under pre-weld cold working and post-weld heat treatment and post-weld cold working. The base metal materials are 5052 aluminum alloys with filler metal of ER5356. A series of experiments including tensile test, microhardness test, optical microscope metallography observation and SEM(Scanning Electron Microscope) were used to determine and analysis the relationship between properties and microstructures.
A series of experiment results indicated that pre-weld cold working can increase the strength and improve the quality of 5052 aluminum alloys. After pre-weld cold working of weldment can improve the mechanical properties(tensile strength and microhardness) of HAZ(Heat-Affected Zone).And post-weld with 350℃,4 hour heat treatment can not improve the mechanical properties of 5052 aluminum alloys. The result form SEM observations indicated that ductile fracture surface occurred in all tensile tested specimen no matter what treatments.
5052-H32鋁合金電阻點銲拉剪強度之韋伯可靠度分析
No full text[[abstract]]5052-H32 aluminum alloys, with the effects of resisting weather and its proper intensity, has the advantage of applying to the outside plate of cars. Besides, due to the prosperous development of 3C(computer, communication, consumptive electronic product) in Taiwan, 5052-H32 aluminum alloys have the qualities of light weight, proper intensity, not affecting communication and not conducting magnetic, so it is noticed in the applicative field.
5052-H32 aluminum alloys, used in the research, is aluminum- magnesium alloys. Through processing hardness and steady treatment, its intensity is medium, matching the AC spot welding machine . In the best welding parameter, by the test of tensile-sheer strength ,we studied the rang of tensile-sheer strength, and then by analyzing reliability , we discussed the reliability of welding parameter.
After studying, we discovered that the best welding parameter of 1.0mm’s 5052-H32 aluminum alloy is 17.1KA welding current, 130kgf electrode force, 13cycles, 17cycles, 21cycles holding time.
In addition, from the micro-structure of nugget and the test of micro-hardness, the structure around nugget is divided into base material, heat-affected zone(HAZ) and re-melted zone. The micro-hardness value of base material is the largest, the micro-hardness value of re-melted zone is the second, and the micro-hardness value of HAZ is the smallest.
The Weibull modulus, m, of the welding plate which is used to test the intensity of tensile-shear strength is between 2.45 and 10.96. Under all conditions, Weibull modulus, m, is over 1 and it’s wear-out mode destruction, which proves that it is practical to use 50KVA AC spot welding machine to welded 5052-H32 aluminum alloys.

KETAHANAN KOROSI PADUAN Al-Mg 5052 DI DALAM AIR PENDINGIN NETRAL MENGANDUNG KLORIDA
Get PDFKETAHANAN KOROSI PADUAN Al-Mg 5052 DI DALAM AIR PENDINGIN NETRAL MENGANDUNG KLORIDA. Paduan Al-Mg 5052 adalah material yang biasa digunakan untuk kelongsong elemen bakar nuklir karena serapan fluks netronnya rendah dan tahan korosi di dalam air demineralisasi pada kondisi operasi reaktor. Makalah ini difokuskan untuk mengetahui ketahanan korosi paduan Al-Mg 5052 di dalam air dengan pH netral dan mengandung klorida sebagai pengganti air demineralisasi pendingin primer Reaktor Serba Guna GA Siwabessy (RSG-GAS). Penelitian mencakup pengukuran laju korosi menggunakan metode Tafel, prediksi mekanisme korosi menggunakan metode voltametri siklik dan analisa produk korosi dengan metode difraksi sinar X. Percobaan dilakukan dengan variasi temperatur 30°C, 35°C, 40°C, dan 45°C, serta variasi konsentrasi larutan natrium klorida 0,05 M, 0,25 M, dan 0,5 M. Hasil penelitian ini menunjukkan bahwa paduan Al-Mg 5052 terkorosi dengan kategori “dapat diabaikan” hingga “sedang” dalam larutan natrium klorida menjadi produk yang larut dalam air pada satu tahap reaksi oksidasi irreversible.
