A novel, integrated, fast, and inexpensive process for the preparation of dense Ba (1− x ) Eu Al 2 Si O 8 thin ceramic specimens damage sensor applications is reported. The processing approach involves a combination combustion synthesis powders spark plasma sintering (SPS) consolidation to densities close 100% relative density. porous by resulted in particle (agglomerate) sizes that were on average 421 nm, as determined from dynamic light scattering, almost complete reduction initial 3+...

Nanostructured yttria‐stabilized zirconia powder (fully and partially stabilized) was densified using simultaneous applied current pressure varying displacement control rates for application. The were found to significantly affect densification as well the final density of products at all temperatures in study. higher than those previously reported without In addition effective activation energies are affected by rates, highlighting importance application method.

In order to determine the electrochemical behavior against corrosion of different commercial biomaterials, in this study results evaluation titanium implants are reported. The evaluated were purchased randomly with suppliers. biomaterials subjected studies potentiodynamic polarization curves, open circuit potential measurements, linear resistance and impedance spectroscopy measurements a 0.9% NaCl solution. showed that chemical composition corresponds commercially pure Ti or alloy Ti6Al4V....

Metal matrix composite (MMC) are engineered materials manufactured by the action of incorporated reinforcement into metal matrix. As a result, stiff and hardened reinforcing phase in metallic is obtained. The includes non-ferrous structures; meanwhile phases comprise non-metallic particulates. purpose this paper to investigate microstructural electrochemical behavior Al-Mg reinforced with SiC particles. Aluminum-Magnesium was vortex method. particles were mixed steel tubes at 1500 rpm molten...

The chemical composition of metallic AlZnAg alloy is related with microstructure in order to know their influence on electrochemical degradation. has been characterized by high transmission electron microscopy energy-dispersive X-ray. behavior tested potentiodynamic polarization tests. In addition, weight loss analysis was carried out for the corrosion rate. tests results showed significant silver concentration dissolution reactions Al-matrix, solid solution rich-Zn, and AgZn3 precipitate...

Aluminium-zinc alloys were added with silver micro-constituent by vortex method and hot-rolled. The understanding of microstructure-chemistry relationship during the electrochemical oxidation effect additions on corrosion behavior have been investigated. results potentiodynamic polarization curves transmission electron microscopy (TEM) energy-dispersive X-ray (EDX) revealed importance addition in microstructure. Ag content significantly influences a-Al, h-Zn e-AgZn3 phases. investigations...

General information approach that includes description physical model used in order analyze behavior its design considered. Shuttle beams conventional electrothermal were modified. Pneumatic microactuators implemented along shuttle. The was designed with silicon material. characterized through coupled electro-thermomechanical analysis using...

On the one hand, Artificial Intelligence (AI) is solving everyday problems that until recently were impossible to imagine solving. ¿How can a powerful supercomputer be program med solve all kinds of algorithms? Phyton (multi-paradigm programming), big data (data intelligence), help us such complex with multifunctional computing applications, name just few. The goal this work design an automated prototype from 3D CAD files create world new possibilities and generate knowledge in field...

In the present work, we studied nanostructural behavior of a denominated alloy Clad- Zinag, which is composed single layer Zinag coated on both surfaces by an aluminum film. The was then deformed two different processes, one in superplastic conformed technique applied and second way tensile testing. For techniques, examined analyzed viewing materials topography with atomic force microscope (AFM). From these techniques were able to observe processes plastic deformation presence marks...

In this work one presents the study realized to compound materials: a) Zn77.0-Al22.0-Ag1.0 (wt. %) [Ternary Alloy], b) Zn77.0-Al22.0-Ag-1.0 [Compound Material 1] reinforced with 5 % of NaCl, and c) Al77.0-Zn22.0-Ag1.0 %)/Si [compound 2], materials were incorporated by means alloyed mechanic in a time grinding 7 hours. The microstructural characterization was of: Diffraction beams-X (DRX), Scanning Electronic Microscopy (SEM) Microhardness Vickers (HV). aim effect microstructure hardness...

Los fraccionamientos en el Área Metropolitana de Guadalajara (AMG) acceso restringido se han convertido un modelo espacios segregados las periferias ciudades. Dichos modelos desarrollo sufrido grandes transformaciones significativas cuecas urbanas del territorio mexicano, ya que trata viviendas con mayores rezagos, ocasionando una mayor fragmentación públicos, propiciando la coexistencia sociedad polarizada. El cambio paradigma visto desde urbanización zonas alto riesgo, es incorporar...
