The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...

Hexagonal close-packed (hcp) iron carbides play an important role in steel processing and in steel products. The recent discovery of novel ultrafine (2-5 nm) iron carbide (ε'-Fe2+xC) precipitates in TRIP steel sheds a new light on the hcp family of carbides. Here we present a first-principles study on the relative stability, and the electronic, magnetic properties of the ε'-Fe2C phases. Differe...

Carbon fiber reinforced polymers strengthen steel structural elements. These structural elements are normally subjected to static, dynamic and fatigue loadings during their life-time. CFRP laminate is commonly used structures under the subjected loads. A number of focused on the characteristics of CFRP sheets members under static, dynamic and fatigue loadings. is a gap in understanding the bond...

The core loss of electrical steel is defined as the dissipation of electrical energy in the form of heat during magnetization by an alternating current. Many efforts have been made to reduce the core loss. Numerous parameters, including the chemical composition and the metallurgical technology, influence the properties of the steel. Electrical steel sheets are mainly produced from Fe-Si-C alloy...

In order to investigate the structure of Fe–Zn phase in a commercial galvannealed IF steel sheet, the electron diffraction and composition of phase in a commercial galvannealed IF steel sheet were studied by transmission electron microscope (TEM) and X-ray energy dispersive spectroscopy (EDX). The cross-sectional TEM specimen was prepared using focused ion beam (FIB) technique which was also in...

We have taken advantage of the native surface roughness and the iron content of AISI 316 stainless steel to directly grow multi-walled carbon nanotube (MWCNT) random networks by chemical vapor deposition (CVD) at low-temperature (1000°C) without the addition of any external catalysts or time-consuming pre-treatments. In this way, super-hydrophobic MWCNT films on stainless steel sheets were obta...
