for the first time, this research reports the formation of nanoporous layers of metals on the surface of metal substrates by raney method and their conversion to corresponding porous perovskite layers. the noble metals doped perovskites are used as catalytic converter for reducing automotive pollutants. the use of perovskite as a substrate for the noble metals can reduce the need for such metal...

Lightweight foam sandwich structures have excellent energy absorption capacity, combined with good mechanical properties and low density. The main goal of this study is to test the application an innovative hybrid protective device in offshore wind turbine (OWT). results are useful for structure applications. Different lightweight materials (aluminum foam, agglomerated cork, polyurethane foam) ...

A numerical investigation on Latent Heat Thermal Energy Storage System (LHTESS) based an aluminum foam totally filled with phase change material (PCM) is accomplished. The PCM used a pure paraffin wax melting over range of temperature and high latent heat fusion. LHTESS geometry under vertical shell tube. corrugated internal surface the hollow cylinder assumed at constant above temperature. oth...

In this study, metal matrix-based composite (MMC) was subjected to Equal Chanel Angular Pressing (ECAP) in several passes determine the influence of deformation on hardness samples. Composite based A356 aluminum alloy and reinforced with Fly Ash (FA) particles obtained by compo casting method. The microstructural analyses microhardness measurements were performed cast pressed Vickers measuremen...

Die casting is forcing molten metal into a mould with high pressure. has two dies namely moving die and fixed where the one will move over die. majorly used for high-volume production. This paper focused on physical phenomenon of (moving die) using different alloy materials variable material chemical compositions. The numerical analysis carried out process to determine crack formation zone by t...

This research studies the effect of flow rate on pouring molten metal into mould so that can be controlled. Furthermore, this preheating temperature inside cavity maintained, especially for narrow holes. The process starts with making engine cylinder head pattern and gating system using a three-dimensional printer polylactic acid resin. are combined coated layer cement plaster, silica sand kaol...

: In this work, we have proposed a concept for the generation of three-dimensional (3D) nanostructured metal alloys of immiscible materials induced by megahertz-frequency ultrafast laser pulses. A mixture of two microparticle materials (aluminum and nickel oxide) and nickel oxide microparticles coated onto an aluminum foil have been used in this study. After laser irradiation, three different t...
