    Description / Table of Contents: Riassunto Si mostra che lo stato quasi cristallino può essere formato in AlCr mediante una trasformazione dello stato solido dalla fase amorfa mediante irradiazione ionica a 150°C con ioni di Xe a 600 keV.
    Notes: Summary We have shown that the quasi-crystalline state can be formed in AlCr by a solid-state transformation from the amorphous phase by ion irradiation at 150°C with 600 keV Xe ions.

    Notes: Thermal and ion-induced reactions in codeposited, multilayer and bilayer Al-Ti and Al-Hf structures were studied by transmission electron microscopy and Rutherford backscattering. A metastable Al3 M (M being Ti or Hf) phase was found by both ion beam mixing and thermal annealing. The metastable phases have a cubic structure with lattice parameters a=3.98±0.01 A(ring) and 4.08±0.01 A(ring) for Al-Ti and Al-Hf, respectively, at a composition of Al3M. The metastable phase transforms to the tetragonal equilibrium compound at annealing temperatures approximately 400 °C. The effectiveness of ion beam mixing is demonstrated by its lower formation temperatures and faster reaction rates. The thermally induced metastable phase formation is ascribed to a lower nucleation barrier than that of the equilibrium phase.

    Notes: Measurements of the low-temperature mixing of several 5d–4d bilayers by 600 keV Xe ions have strongly supported the assumption of a thermal spike mechanism. Quite disturbingly, however, the Au-Ag mixing rate appeared to exceed theoretical predictions by about a factor of 3. A closer examination of this system shows the discrepancy to be caused by the formation of a strongly nonuniform Au surface structure during irradiation. An improved value for the mixing rate is in reasonable agreement with predictions.

    Notes: The ion irradiation stability of the CsCl phases CoAl, IrAl, SiRu, and AuZn has been investigated. Thin-film (∼500-A(ring)-thick) transmission electron microscopy samples were irradiated with Xe to a maximum dose of 4×1015 ions/cm2 at room temperature. Irradiation-induced transformations in the compound samples were examined by transmission electron diffraction. The alloys CoAl, IrAl, and AuZn remained crystalline while SiRu became amorphous. Analysis of our findings and other previously reported experimental results indicate that CsCl compound stability under ion irradiation is strongly correlated with atomic mobilities.

    Notes: As part of an ongoing effort to produce high-Tc superconducting layers by ion-beam mixing, the mixing of Cu and Y was studied at both liquid nitrogen and room temperature, using 600-keV Xe ions and Y film thicknesses representative of multilayer mixing experiments. At low temperatures the mixing rate was found to agree with predictions based on thermal spike effects. At higher temperature the mixing is dominated by the rapid formation of the Cu7 Y phase.

    Notes: Conclusion The avant-garde has defined itself not only by what it has opposed; it has come to show a specific content and character best shown in Poggioli's masterful portrait. Lukacs-Bloch-Adorno stood in a complex but unclarified relation to the avant-garde; their failure to clarify this relation constitutes a limitation on their sociology of music. One wishes for a new Max Weber to put their broad statements to some kind of historical test. However, the condition of music today calls for a different kind of sociology than they produced; the fragmentation of music into a multiplicity of styles and audiences, the cornucopia of choices that make available almost all musics from all eras throughout the world, the specialization and fragmentation of audiences for the classics, for avant-garde experiments, for folk music, ethnic musics, for rock, punk, and whatever else, the co-existence of more than one style of composition, all require a sociology of music that is not encompassed by a single philosophical approach.
