Densification and Mechanical Properties of Nanocrystalline FeAl
… measurements were performed on nanocrystalline FeAl specimens sinterforged to full density. The tests were conducted over the temperature range of 500--600°C, and using punches with diameters of 0.5 and 0.2 mm. For specimens sinterforged at 500°C, a decrease in creep rate was observed …

Estudio teórico de catalizadores intermetálicos PdGa y de la aleación FeAl
… del hidrógeno sobre el sistema bimetálico B2 FeAl con defectos puntuales. En este caso se determinó la ubicación de la impureza en un sitio intersticial octaédrico y los resultados se compararon con cálculos de densidad funcional y con algunos resultados experimentales de la literatura. En una …

Desarrollo de composites magnetostrictivos de FeAl y FeGa para su aplicación en sensores de deformación
The control of stresses and deformations in the hull of a ship is vitally important for the safety of navigation as well as for its proper functioning. Currently, the control of the good condition of the ship's structure is carried out by the Classification Societies during the regular reviews of …

Defect Structures in Ordered Intermetallics; Grain Boundaries and Surfaces in FeAl, NiAl, CoAl and TiAl
… grain boundary structures in B2 aluminides, FeAl, NiAl and CoAl and <I>L</I>1₀ γ-TiAl were investigated using molecular statics and embedded atom potentials in order to explore general trends for a series of B2 compounds as well as TiAl. The potentials used correctly predict the proper …

Deformation mechanisms in B2 aluminides: shear faults and dislocation core structures in FeAl, NiAl, CoAl and FeNiAl
… B2 aluminides with increasing ordering energy (FeAl, NiAl, CoAl). The simulation results in NiAl were compared with in-situ straining observations of dislocation motion. The dislocations simulated were of (100) and (111) types. The simulations results obtained indicate a strong influence of the …

Experimental Studies on Nucleation, Nanoparticle's Formation and Polymerization from the Vapor Phase
… Different intermetallic nanoparticles (FeAl and NiAl) from the vapor phase has also been prepared, using the same approach.In this work, the fraction of the charged particles generated during the laser vaporization process was used to prepare a new class of nanoparticle assemblies in the …

Atomic and electronic structure of bulk intermetallic and heteroepitaxially grown surface alloys
… the surfaces of the ordered intermetallic alloy FeAl(110) exhibit surface segregation , which changes the Al concentration in the near surface region. The segregation and corresponding concentration change of Al induces a reconstruction on the surface as a function of annealing temperatures. The …

Feeling real in fiction : a study of the phenomenological mimesis of givenness in the novel.
… simple-seeming question: how do novels feal real to us? I argue that what makes any novel, whether realistic or fantastic, feel real is the way in which the reader's unfolding of the novel from the text mimetically parallels fundamental aspects of the phenomenological disclosure of a …

Exportaciones a China y crecimiento económico en América Latina
El crecimiento de las exportaciones a China desde los países de América Latina ha despertado el interrogante sobre el efecto que las mismas pueden tener en el crecimiento a largo plazo de la región. Si bien exportar más a China promueve el aprovechamiento de economías de escala y especialización, …

Information security based on temporal order and ergodic matrix
… cryptosystems, such as RSA, DES, IDEA, SAFER and FEAL, are not ideal for image encryption for their slow speed and not removing the correlations of the adjacent pixels effectively. Another reason is that the chaos-based cryptosystems, which have been extensively used since last two decades, almost …

Intermetallic phases formed during galfanizing
… with the outer part next to the eutectic being FeAl3-Znx. The breakaway phase was FeAl3-Znx and another phase next to the interface was Fe2Al3-Znx. The intermetallic growth is characterized by the growth of Fe2Al3-Znx towards the substrate with a <001> growth direction, following a reaction path …
