    X-ray diffraction characterization of ternary artificial superlattices (1993)

    Notes: Thin films of alternating Au, Ag, and Cu wedge-shaped metal layers were made by magnetron sputtering in order to develop a method for investigation of a multicomponent systems. X-ray-diffraction patterns of all as-deposited samples revealed satellites in the vicinity of (111) reflections, evidence of composition-modulated artificial superlattice formation. The experimental spectra are well explained by the kinematical diffraction theory for imperfect superlattices. Computer simulations have demonstrated extremely high sensitivity to the fluctuations ΔH/H of the superlattice period H. As a result, a rapid and simple method of ΔH/H determination is proposed.

    X-ray diffraction study of surface acoustic wave device under acoustic excitation (1993)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The acoustic field inside a surface acoustic wave device was studied by means of double-crystal x-ray diffraction. Angular satellites in the diffraction pattern were observed due to the coherent scattering on the acoustic superlattice. Satellite dynamics allows determination of the acoustic wave amplitude. Due to the sensitivity of x-ray diffraction to the direction of atomic displacements, the amplitude of different polarization components in the Rayleigh wave can be obtained.

    On the model of metastable phase formation by a diffusion process (1990)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 67 (1990), S. 2904-2907

    Notes: It is proposed that the structure of a new layer AB, which forms between the components A and B, is defined by parameters of two-stage interfacial reactions. The two stages, namely transition of A atoms through the AB/B boundary and rearrangement of atoms in B into AB, have independent rates. In the initial stage of the interaction between the two components the flow through the thin new layer does not control the reaction rate. The high rate of atomic flow through the interface combined with the relatively low rate of diffusion at the interface will result in the formation of metastable (amorphous, quasicrystalline, or crystalline) phases. The additional growth of the layer results in a decrease in the growth rate down to a critical value. The thickness of the metastable layer is thus limited and a stable crystalline phase starts to form at the interface. The critical thickness of the metastable phase depends on the diffusion parameters of the initial and intermediate phases.

    Rapidly solidifed Al-Cr alloys: structure and decomposition behaviour (1986)

    Notes: Abstract Melt-spun ribbons of aluminium containing up to 15 wt% chromium were examined in the as-spun condition and after annealing. The more concentrated alloys contained multi-phase spherulites embedded in an α-Al matrix: chemical microanalysis showed the average composition of the spherulite core to be 22 ± 2 wt% chromium. The kinetics of precipitation at grain boundaries and within the matrix were determined by TEM and X-ray diffraction. Three very similar Al-Cr intermetallic phases are present under equilibrium conditions, but most of the precipitates in the melt-spun ribbons could be identified as Al7Cr.

    Formation of icosahedral phase by solid-state diffusion of alternating thin layers (1992)
    Springer
    Journal of materials science 27 (1992), S. 5553-5557 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Thin alternating layers of Al-Cr were produced by sputtering. Heat treatment transforms them to the icosahedral phase. The effect of the layer thickness on their ability to transform to single-phase icosahedral film was examined and it was found that very thin alternating layers react completely to form a single icosahedral phase, while heat treatment of thicker layers always produced the icosahedral phase with residual aluminium. An attempt has been made to explain the results based on the crystallographic structure of the icosahedral phase.

    The microstructure of rapidly solidified Ti-32wt% Fe melt-spun ribbon (1990)
    Springer

    Notes: Abstract A Ti-32wt% Fe alloy was rapidly solidified by the melt-spinning technique. Three microstructures are found in the melt-spun ribbon of the alloy: the first contains small FeTi particles in aΒ matrix, the second is a cellular microstructure composed ofΒ and FeTi and the third is a eutectic of these phases. The correlation between various solidification and cooling rates across the ribbon width to the three microstructures is explained.
