Friction stir welding (FSW) adalah suatu teknologi pengelasan yang merupakan proses solid-state joining bisa digunakan untuk menyambungkan material aluminium dengan mampu las rendah. Proses FSW memanfaatkan putaran dari tool menggesek dua buah lempengan logam akan disambung. Aluminium 2024 T3 ketebalan 4 mm disambung menggunakan variasi feedrate 13 mm/menit, 15 dan 25 kecepatan spindle 910 rpm ...
In this paper we utilize Support Vector Machines to predict the degradation of the mechanical properties, due to surface corrosion, of the Al 2024-T3 aluminum alloy used in the aircraft industry. Precorroded surfaces from Al 2024-T3 tensile specimens for various exposure times to EXCO solution were scanned and analyzed using image processing techniques. The generated pitting morphology and indi...
The strain-specific modifier Ssm1 is responsible for the straindependent methylation of particular E. coli gpt-containing transgenic sequences.Here,we identifySsm1as theKRAB-zinc finger (ZF) gene 2610305D13Rik located ondistal chromosome4.Ssm1b is amember of a gene family with an unusual array of three ZFs. Ssm1 family members in C57BL/6 (B6) and DBA/2 (D2) mice have various amino acid changes ...
Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain res...
