Friction Surfacing Cladding (FSC) is a relatively new solid state process to deposit thin metallic clad layers on substrates. It employs a hollow rotating tool that supplies the clad material. Frictional and viscous heating take place that soften the clad material and enhance the bonding of the clad material to the substrate. Thin layers of commercially pure aluminium can be deposited well on a...

Accumulative roll bonding is an advanced manufacturing process, which capable of simultaneously refining the grain size into nanometer regime and different metallic sheet materials. Herein, homogenous aluminum/aluminum as well heterogeneous aluminum/steel laminated metal composite (LMCs) are fabricated. The residual stresses experimentally determined by X-ray diffraction hole-drilling method. G...

Electrical-current-assisted friction stir welding (EA-FSW) is a procedure developed for the joining of similar and dissimilar materials. EA-FSW newly invented solid-state process to increase welded components’ efficacy in various applications, such as marine structures. joints have investigated on aluminum–magnesium, aluminum–steel, polymer-to-steel. Similar been performed aluminum, magnesium, ...

Double-clad photonic crystal fiber and double-clad fiber have been widely used in multiphoton-excited fluorescence or second-harmonic generation (SHG) endoscopy. We provide a useful comparison of two fibers used in nonlinear optical microendoscopy. While a double-clad fiber is found to have a higher percentage of the output power from its core, which results in the efficient utilization of the ...

The favorable energy-absorption properties of metal foams have been frequently proposed for damping or anti-crash applications. The aim of this paper is to investigate the endurance of these properties for composite structures, made by a metal or a hybrid metal-polymeric foam used as the core filling of a tubular metal case. The results of experimental tests are shown, run with two types of str...
