Abstract Böhler (or Boehler) W403 VMR is a tool steel with outstanding properties, based not only on a modified chemical composition, but on the selection of highly clean raw materials for melting, remelting under vacuum (VMF), optimized diffusion annealing, and a special heat treatment. This datasheet provides inform…
The formation of barium hexaferrite, BaFe12O19 single phase with nanosize crystalline is very important to get the best performance especially magnetic properties. The samples were prepared by sol gel method in citric acid-metal nitrates system. Hence the mole ratios of Ba2+/Fe3+ were varied at 1:12 and 1:11.5 with pH…
Perovskite lanthanum manganites, especially those doped LaMnO3 (LMO), have shown potentials for applications in magnetic electronic functional materials. Partial substitution of La ion with divalent ions or Mn ion with trivalent ions gives rise to new properties. Substituted LMO has ability for absorbing electromagnet…
CaxNi1-xO was prepared by conventional solid state reaction. The properties of undoped and CaO doped NiO ceramics have been studied. The raw mixture of CaO and NiO were ball milled for 24 hours. The samples were calcined at 1000°C for 2 hours, pressed into pellet shape at 200 MPa and sintered at 1300°C for 4 hours. Th…

Several biodegradable polymers have been explored to develop biodegradable edible films in order to reduce the use of conventional plastics. In this study, edible biocomposite film is made from gelatin filled with Bacterial Cellulose Microcrystal (BCMC). BCMC is produced from nata de coco paste, which is hydrolyzed wi…
This classification system provides a method of adequately identifying PTFE micropowders using a system consistent with that also of another specific classification. These powders are sometimes known as lubricant powders which usually have a much smaller particle size than those used for molding or extrusion. The test…
Selective aerobic oxidations are among the most important transformations in the manufacture of fine chemicals. Traditionally, these processes use stoichiometric reagents, such as permanganate and dichromate, and end up with a large amount of toxic waste. Currently, there is considerable pressure to replace these tech…
Влияние технологических параметров на формирование пристеночного валика при многопроходной сварке в защитных газах Д.С.Бузорина, М.А.Шолохов Для получения качественных сварных соединений при изготовлении ответственных металлоконструкций (мосты, спецтехника, трубопроводы и др.) существуют жесткие ограничения погонной э…

The deformation after ballistic impact loading of silicon carbide reinforced aluminium alloy composite is investigated in this research. The composite consists of 10 % volume fraction of silicon carbide particulate in a matrix of Al-7Si-Mg-Zn alloy and were produced through the squeeze casting process with a pressure…
W.L. Gore & Associates of Newark, Delaware, USA, has expanded its line of Gore Skyflex aerospace materials for sealing applications by developing a low-tack adhesive that makes it easier to readjust sealants in complex structures during installation procedures.
Synthesis of mesoporous silica from tetraethylorthosilicate (TEOS) by using sodium ricinoleic as a template and 3-aminopropyltrimethoxysilane (APMS) as a co-structure directing agents (CDSA) in a volume variation of acid addition has been carried out. Preparation of mesoporous silica was conducted in HCl 0.1 M at volu…
Significance and Use 3.1 The thermal conductivity of carbon refractories is a property required for selecting their thermal transmission characteristics. Users select carbon refractories to provide specified conditions of heat loss and cold face temperatu
Significance and Use 5.1 The sulfated ash can be used to indicate the concentration of known metal-containing additives in new oils. When phosphorus is absent, barium, calcium, magnesium, sodium and potassium are converted to their sulfates and tin (stann
