In this paper, the Accumulative Channel-die Compression Bounding (ACCB) method is investigated as a new method of severe plastic deformation to produce Nano-crystalline bulk metals on the basis of pressing in a channel mold. Aluminum as One of the most usable metal in industry is processed using this method. Analyzing the processed samples show that after four passes of ACCB method, the ultimat...

The structures realized using sandwich technologies combine low weight with high energy absorbing capacity, so they are suitable for applications in the transport industry (automotive, aerospace, shipbuilding industry) where the “lightweight design” philosophy and the safety of vehicles are very important aspects. While sandwich structures with polymeric foams have been applied for many years, ...

OBJECTIVE Four cases of pituitary adenoma among employees at a primary aluminum production factory were identified over a five year period by a community physician. The objective of this investigation was to determine whether there has been a comparable high incidence in other aluminum factories, and if particular jobs, departments, or activities in the industry are associated with higher rates...

Researchers have turned to search for new materials that will meet all the aerospace industry requirements. When it is almost impossible achieve this with a single material, composite been studied, and there great developments in field. Many elements are used aircraft construction, but aluminum most preferred due its low density, good castability, high strength, corrosion resistance, fatigue st...

Polymeric aluminum ferric sulphate(PAFS) was prepared from high-sulfur bauxite flotation tailings and red mud by roasting, acid leaching polymerization. The effects of temperature, time, liquid-solid ratio on the rate Al3+ Fe3+were investigated. optimal conditions are as follows: temperature 100℃, time 90 min, sulfuric concentration 4.5mol/L 5 mg/L. Infrared spectroscopy X-ray diffraction analy...
