Transverse structure of magnetization in a ferromagnetic film induced by magnetic field electric current has been analyzed. Two steps arising exchange spring evolution are shown. The first one (weak current) is gradual twisting aside from the wire axis. Above some critical transient area compressed and localized near middle plane. In presence additional conductive layer becomes asymmetric resul...

Even below its normal melting temperature, ice melts when subjected to high pressure and refreezes once the pressure is lifted. A classic demonstration of this regelation phenomenon is the passing of a thin wire through a block of ice when sufficient force is exerted. Here we present a molecular-dynamics study of a nanowire cutting through ice to unravel the molecular level mechanisms responsib...

This research was conducted to analyze the hardness, microstructural morphology, and crystallography of MgB2 compound in form a SS 304-sheathed superconducting wire. wire with 304 outer sheath manufactured using an ex-situ rolling process. The results Vickers hardness test load 0.3 N showed value 355.1 HV. observations SEM-EDS (scanning electron microscopy-energy dispersive spectroscopy) agglom...

Despite the high efficiency and low cost of wire + arc additive manufacture (WAAM), epitaxial grown columnar dendrites WAAM deposited Inconel 718 cause inferior properties severe anisotropy compared to wrought components. Fundamental studies on influence one-pass cold warm rolling hardness microstructure were investigated. Then interpass tensile also analyzed. The results show that increases di...

Post-build rolling can mitigate residual stress (RS) and distortion in large-scale components built by wire arc additive manufacturing (WAAM). In this study, based on numerical simulations that considered both WAAM deposition vertical rolling, the mechanisms of rolling-enabled mitigation RS a WAAM-built steel wall are elucidated. The influences process configuration condition, such as roller de...

Limited by the deficiency of the finite element method (FEM) to deal with infinite domain problems, the traditional FEM rolling model is not suitable enough to study the effect of the complex internal stress of the incoming strip on hot rolling deformation. To solve this problem, the finite element and infinite element (FE-IE) coupling method is adopted, where the finite element is for the roll...

Aluminum is one of the most common deoxidizers; when it used in melt, refractory inclusions alumina are formed. The presence these non-metallic negatively affects purity liquid steel, mechanical properties, makes casting difficult due to tightening steel-pouring fittings. modification with calcium promotes formation aluminates, which leads an acceleration their removal from metal a higher ascen...

Asymmetric sheet rolling is a process used when there are differences in any technological parameters the horizontal plane across width of deformation zone or vertical between top and bottom surfaces zone. Asymmetry can either have random causes, it be created purposefully to reduce force, improve flatness, minimize ski effect, obtain thinner sheets for grain refinement improvement texture mech...
