Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

Currently, liquid metal filtration in casting process is a familiar refining technology for casting process. This technique be able to exist removed the inclusions inside the melts and subsequently improves the mechanical properties of the product. Furthermore this will also improved the surface finish and tightness of cast product. This significantly reduced the rework cost. The present resear...

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...

Welding is a suitable and better process to manufacture complex objects for aerospace, naval, automotive structures. Service conditions complexity in load acting force the manufactures make joints between dissimilar materials. Thus, there need efficient welding techniques form sound an understanding of imperfections their effects. In this study attempt has been made joining feasibility aluminum...

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...

3 Ordered Cu-(35–50) at.% Pd alloys (B2-type superstructure) have a high corrosion resistance and are distinguished by possessing very low electrical resistivity r » (4–8) × 10 ohm m (1), two properties which make them of interest to researchers developing functional materials. However, wide-scale use of these alloys is hindered by their relatively poor strength properties: the yield stress of ...

During temperature cycles, metallic alloys for high temperature applications are usually oxidized with formation of an external protective oxide scale, but they loose it during the cooling. This problem of oxide spallation can be studied by specific tests of cyclic oxidation but first indications can be provided by analyzing the cooling parts of thermogravimetry curves. This possibility was stu...

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 ...
