This study reveals the characteristics of switched reluctance motors (SRMs) made by blanking (a) 20HX1300 high grade low-iron-loss silicon steel (0.20mm thickness) and (b) 2605SA1 amorphous alloy (0.025mm thickness). The is an innovative technology for mass production efficiency amorphous-alloy-motor. impact processing methods on magnetic properties are evaluated using ring cores processed foll...

A round-robin experiment *re to be carried out by 6 laboratories in Japan (Nishikawa; Tokyo Inst. Tech., Sakurai and Igata; Univ. of Tokyo, Ishikawa; Hitachi, Tanino; Nippon Steel Corp. and Nakamura; Osaka MT.) under the normal operating condition (T<lOO°K,.~lse fraction-75%~~ Pc10' torr). Fe-Cr-Al and W-25%Re alloys, which are divided fran a single wire were chosen as the specimen materials. A...

6063 aluminium alloy is widely used in architectural applications such as window and door frames because of its nice appearance acceptable strength. Its major alloying elements are magnesium silicon. Not many studies focused on the influence plastic deformation content post-processing quality corrosion resistance have been published. Considering that variation chemical composition could propert...

To discuss the possibility of phosphorus removal from silicon by the solidification refining with Si–Al melts, the distribution of phosphorus between solid silicon and the liquid Si–Al alloy at 1173–1373 K was investigated. In the present study, the distribution of phosphorus was examined by the temperature gradient zone melting method, where a phosphorus containing molten Si–Al zone was passed...

One of the most exciting areas in lithium ion batteries is engineering structured silicon anodes. These new materials promise to lead the next generation of batteries with significantly higher reversible charge capacity than current technologies. One drawback of these materials is that their production involves costly processing steps, limiting their application in commercial lithium ion batter...

Biomorphic silicon carbide stands as a new class of materials fabricated by reactive infiltration of molten silicon in carbonaceous preforms obtained from wood pyrolysis [1]. The basic material is a Si/SiC composite, in which the SiC forms a skeleton that replicates the wood microstructure and the unreacted Si fills the pores. Silicon can be removed from the composite creating a highly porous S...

Cone-shaped nanostructures of mixed composition (nanocones) and largely graphitic nanofibers were synthesized on silicon substrates using iron/platinum alloy nanoparticles as the catalyst in a direct-current plasma enhanced chemical vapor deposition reactor. The catalyst nanoparticles were monodisperse in size with an average diameter of 3 (±1) nm. The nanocones were produced on laterally widel...

To exploit Rashba effect in a 2D electron gas on silicon surface for spin transport, it is necessary to have surface reconstruction with spin-split metallic surface-state bands. However, metals with strong spin-orbit coupling (e.g., Bi, Tl, Sb, Pt) induce reconstructions on silicon with almost exclusively spin-split insulating bands. We propose a strategy to create spin-split metallic bands usi...
