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...

In scanning display systems, high horizontal and vertical resolution, and high refresh rate requirements translate into large mirror-size scan-angle product and high scanner-frequency requirements. A comparison between published scan-angle mirror-size product values for MEMS scanners and a Steel mechanical scanner is presented. Current performance levels of Steel mechanical scanners are better;...

Many metal alloys are susceptible to corrosion, particularly after processing steps such as welding. Chemical vapor deposition (CVD) is an effective way to modify metal surfaces and impart specific physical and chemical properties. A hydrophobic, nanosegmented silicon oxide coating derived from the discrete cluster molecule H8Si8O12 has been shown to chemisorb to 302 and 304 stainless steel. To...

Thin-fi lm silicon solar cells, including hydrogenated amorphous silicon (a-Si:H) single-junction and amorphous/microcrystalline silicon (a-Si:H/ μ c-Si:H) tandem-junction solar cells, are promising candidates for the global terawatt-scale deployment of photovoltaics thanks to the abundance and non-toxicity of their raw materials, and mature fabrication processes. [ 1 , 2 ] Compared to their tr...

Lightweight advanced high strength steels (AHSS) with aluminum contents between 4 and 12 weight percent have been the subject of intense interest in the last decade because of an excellent combination of high strain rate toughness coupled with up to a 17% reduction in density. Fully austenitic cast steels with a nominal composition of Fe-30%Mn-9%Al-0.9%C are almost 15% less dense than quenched ...

this research was conducted to study the effect of lime based flux with the composition of cao-20%caf2-8%feo on simultaneous removal of phosphorus and sulfur from hot metal. the effects of na2o and oxygen blowing were also studied. the experiments were performed using an induction furnace and hot metal produced in isfahan steel company in the temperature range 1350-1450 ºc. the results showed t...

A corrosion-inhibiting mixture of compounds has been developed for addition to the water used to rinse metal parts that have been cleaned with aqueous solutions in preparation for adhesive bonding of the metals to rubber and rubberlike materials. Prior to the development of this corrosion inhibitor, the parts (made, variously, of D6AC steel and 7075-T73 aluminum) were rinsed by deionized water,...

Southwest Research Institute (SwRI ® ) conducted a study to determine whether pulsed x-ray sources used in conjunction with amorphous silicon real-time imaging plates could provide equivalent radiographs to those obtained using isotopic sources with conventional radiographic film for inspection of schedule 40 steel pipe. Radiographic procedures for the two techniques were developed; test welds ...
