In this study, HEA/Al composite interlayer was used to fabricate Ti/Mg bimetal composites by solid-liquid compound casting process. The Al layer prepared on the surface of TC4 alloy hot dipping, and FeCoNiCr HEA magnetron sputtering onto layer. influence thickness pouring temperature interface evolution investigated based SEM observation thermodynamic analysis. Results indicate that sluggish di...

Equal channel angular rolling (ECAR) process is one of the severe plastic deformation (SPD) methods that have been used to make ultra-fine grain (UFG) materials with improving the mechanical properties of samples. After performing the process at several paths, a large strain is applied to the material that can cause decreasing the grain size and improving the mechanical and physical properties ...

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. They made by welding resistive material to commonly available carbon steel pipes. The production of pipe bends with supercritical bend 0.7D, which part serpentine systems, is very complex and technologically demanding because often undesired cracks occur. To increase the ser...

Photocatalytic degradation of fast green using pure and N-S codoped bimetal nanoparticles CeCdO3 has been studied. The CeCdO3 nanoparticles were synthesized by wet precipitation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and FTIR. The rate of photocatalytic reaction was examined spectrophotometrically using pure and N, S-codoped catalyst. The effect ...

Nanofabricated photonic materials offer opportunities for crafting the propagation and dispersion of light in matter. We demonstrate an experimental realization of a two-dimensional negative-index material in the blue-green region of the visible spectrum, substantiated by direct geometric visualization of negative refraction. Negative indices were achieved with the use of an ultrathin Au-Si3N4-...

The broadband narrow pulse self-focusing ultrasonic transducer was designed for the special structure of the column holes, and used to do the research for the testing of bonding layer of metal composite material with F-scan ultrasonic imaging system. The copper-steel boding layer of bimetal rotor is connected by diffusing welding. There may be delamination flaws existed here. The depth and rang...
