The strength and ductility of microcrystalline and nanocrystalline tungstsen carbide–cobalt (WC–Co) cermets have been evaluated by employing a stored energy Kolsky bar apparatus, high-speed photography and digital image correlation. The test specimens were thin-walled tubular Al7075-T6 substrates 250 μm thick, coated with a 300 μm thick microcrystalline or nanocrystalline WC–Co layer with an av...

Fatigue damage detection and its classification in metallic materials are persistently challenging the structural health monitoring community. The mechanics of fatigue is difficult to analyze further complicated because presence notches different geometries. These act as possible crack-nucleation sites resulting failure mechanisms that drastically from one another. Often, sensor-based tools use...

Producing items that are of both high quality and long lasting is a difficult task for companies right now. There huge need wide range engineering materials in today’s technologically advanced globe. The strength qualities the material determine amount may be used. Due to its excellent mechanical low density, aluminum-7075 alloy mostly employed transportation applications such as aerospace, mar...

Nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. In this paper, ultrasonic assisted turning (UAT) isperformed to create the micro textures on the flat faces. Micro surface texturing ismade on the Al7075-T6 by the UAT in the face turning process. Then, the influences of cutting speed feed, vibration direction and vibration ampl...
