in this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. in this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

Havacılık, biyomedikal ve otomotiv endüstrisinde alüminyum alaşımlarının kullanımının yaygınlaşmasıyla birlikte, bu malzemelerin işleme davranışları problemleri son yıllarda ilgi konusu olmuştur. Kuru işlemede, gibi yüksek plastisiteye sahip (sünek) metaller, takım-talaş ara yüzeyinde geniş temas alanı, sürtünme katsayısı sıvanma (adezyon) özellikleri buna bağlı olarak güçlü bir talaş yığılması...

Water-soluble metal working fluids are used for processing of aluminum alloy materials. This short article describes properties of new additives in water-soluble metal working fluids for aluminum alloy materials. Many half esters or diesters were prepared from the reactions of higher alcohols with acid anhydrides. Interestingly, diesters of PTMG (tetrahydrofuran oligomer, MW = 650 and 1000) and...

In the present study, corrosion behavior of aluminum Al-7075 tempered (T-6 condition) alloy was evaluated by immersion testing and electrochemical in 1.75% 3.5% NaCl environment at acidic, neutral basic pH. The data obtained both tests (potentiodynamic polarization impedance spectroscopy tests) that rate specimens is minimum for pH=7 condition solution due to formation dense well adherent thin ...

The evolution of the overall microstructure and contribution constituent second phase particles during accelerated corrosion AA 7075-T651 warrants further scrutiny. A correlative microscopy-based approach was employed to study damage in subjected potentiodynamic polarization. X-ray Computed Tomography (XCT) scanning electron microscopy were used track initiation propagation globally at specific...
