The vapor, such as Mg- Al eeutecticaB2O2 gAl O g and Al 2O gproduced during the process of combustion synthesis, reacted with each other to yield Al B2 nanowires by vapor-solid VS mechanism and the corresponding model was also proposed. The damage was low and increased with temperature, SiCp proportion and Cu matrix composition. Efecto del calcio sobre la toxicidad aguda de aluminio en alevines de trucha arcoiris Oncorhynchus mykiss expuestos en aguas de diferente pH.

Full Text Available In the present research, the responses of unprotected and anodized aluminium specimens are compared after they aleaciob been exposed to 12 different atmospheres. In present article it is dealt with a brief look to the tipology and properties of the structural aluminium alloys, and it is described the content of Eurocode 9 “Design of aluminium structures”, approved by CEN European Committee for Standardization in may that it is foreseen to be published in Spanish by AENOR in short time.

The results obtained show that the coating projected with an oxygen pressure of 78 psi and an acetylene pressure of 8 psi have the better wear resistance compared with the substrate and the others treatments deposited.

This study provides a new insight for preparing Mg composites. Twenty patients were divided into two groups. The results of physicochemical analysis revealed that the concentrations of In the paper a brief review of filiform corrosion on coated aluminium is shown.


Previous surfacetreatment, color and thickness of the anodized layer. Estas alteraciones tienen lugar gradualmente, excepto en el caso de dos modos opticos longitudinales, observados en las posiciones 1,27, 1,27, 0 y 1,2, 1,2, 0,2 en el espacio. The inflammatory process was measured at postoperative on the first, third and seventh days. The variables analysed were the chemical content and the eitectica size of the solid agents, the melt temperature and the injection rate.

The characterization of hematite before and after modification with aluminum hydroxide was studied by X-ray diffraction, scanning electron microscopy, EDS and Bet. Aleacuon applications are growing up, specially in the transportation industry.

Results of the combination of high power YAG beams with small fiber diameters and specific filler wires are presented. The significant influences have been observed in the argon shielding during diffusion bonding process. The wear test was carried out ina pin-in-disc machine, at various rates and wear pressures.

Also, a comparative study between a aluminium alloy and pure aluminum was carried out, showing the feasibility of attaining similar tribological behavior between a conventional alloy and pure aluminum prepared by powder metallurgy techniques. The activation energy associated to all eutectixa reactions was determined by Differential Scanning Calorimetry.

Direct reading spectrochemical determination of aluminium, iron and silicon in fluorite; Determinacion espectroquimica de lectura directa de aluminiohierro y silicio en fluorita.

However, its wide application as structural material needs of the proper development of their joining process. The influence of the composition of the crystalline phases in the degree of the ceramic lining attack is also studied.

Aleación fusible

Scientific evidences show that Al Quran has the truth massages, although it was released far before the finding of modern sciences. Full Text Available An aleaacion of the results regarding the permanent contact reaction that occurs between the Mg dissolved in molten aluminum and SiO 2 particles is presented.

In two of the preceeding decades a great effort was realized to reduce costs in the traditional hydrothermal sealing process in deionized boiling water SHT, a very expensive eutectlca due to its endurance and high temperature on which it develops. The group treated received laser therapy in the temporomandibular articulations and in the muscles affected.


Full Text Available Das Interview ist nach wie vor das beliebteste sozialwissenschaftliche Verfahren des Datengewinns. Potato Solanum tuberosum L. The major findings related to the formation mechanism of twins and mechanical behavior of nanotwinned metals include the followings: The role anions on the synthesis of Al OOH nanoparticles using simple solvothermal method.

The prealloyed copper powders, atomized in inert gas and containing 3 wt. Full Text Available The present demand on alloy production with improved quality requires the optimization of the metallographic procedures used a,eacion its characterization.

This simple method can be interesting to monitoring and controlling the oxidation process.

Some of these parameters belong to the welding process, as for example the welding speed, intensity and voltage while others are from the material and tooling features, as for example foaming material and tooling design.

It was found eutecticaa the instability of the keyhole during welding was a dominant cause of pore formation while hydrogen rejection played an insignificant role. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. The texture of the alloy is formed by the fiberi. Formas de hierro y aluminio en suelos con diferentes usos en la zona norte del departamento del Magdalena, Colombia. This work investigates the use of nitrides as reinforcement for composite materials, with Al matrix, obtained by powder metallurgy and extrusion, presenting their microstructural features and their mechanical characteristics.
