fiber metal laminates are hybrid laminates consisting of thin alternating bonded layers of aluminum and fiber/epoxy. arall (aramid aluminum laminate) and galare (glass fiber reinforced aluminum laminate) are specific kinds of fiber metal laminates that consist of thin aluminum sheets along with kevlar/epoxy and glass/epoxy composite layers, respectively. in this study, nonlinear tensile behavio...

This paper gives research results about commercial examination of aluminum alloy-based products according to industrial standards. Results of metallographic tests of extruded aluminum microstructure shown in this paper indice that irregular deformation of material leads to microstructure variations through certain zones of the product. That influences mechanical properties, and it can even be t...

The specification of an aluminum alloy for a cast component is based upon the mechanical properties it can achieve. For the designer and purchaser, it is vital to understand that the properties obtained from one particular combination of casting alloy, foundry practice and thermal treatment may not be identical to those achieved with the same alloy in a different foundry or with a different the...

The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were ...

Magnesium and its alloys are active materials, and the oxide can easily form when they react with air and moisture (Czerwinski 2002). In addition, magnesium and its alloys are flammable and require strict safeguards during the manufacturing process. These disadvantages make the processing of magnesium alloys into finished products more challenging. These drawbacks cause defects such as cracks, ...

aa8090 is an extra light and deformable group of lithium containing aluminum alloys which have recently replaced some aerospace aluminum alloys, such as 2000 and 7000 series, due to their higher elastic modulus and lower specific weight. in this study, aa8090 matrix composites containing 3, 6 and 9 vol.% sic were cast using a modified stir casting method. the casting billets were deformed thoug...

We have measured the linear polarization induced in a beam of submillimeter radiation when it is obliquely reflected by a flat mirror made of aluminum alloy. For angles of incidence in the range 15 degrees -45 degrees , we measured induced polarizations in the range 0.05%-0.25%. Our measurements are within a factor of 2 of theoretical predictions. We conclude that astronomical telescopes that i...
