ISSN: 0392-6737Keywords: Mechanical and elastic wavesSource: Springer Online Journal Archives 1860-2000Topics: PhysicsDescription / Table of Contents: Riassunto Generazione della seconda armonica ottica è ottenuta nei monocristalli di Si e Ge con impulsi laser di 10 ps, a 527 nm, e con densità di energia inpingente superiore all soglia per la fuzione del reticolo cristallino. Si osserva che la seconda armonica mantiene la propria dipendenza dall' orientazione cristallografica, indipendente dal valore della densità di energia che è incidente sulla superficie cristallina, fino alla soglia del danno. Il mutamento d'intensità di generazione a secondo orientazione cristallografica e piano di polarizzazione è stato analizzato in funzione di vari contributi probabili.Notes: Summary The crystallographic dependence of optical-second-harmonic generation (SHG) in Si and Ge single crystals is obtained with 10 ps pulses at 527 nm and at incident fluences above the threshold for laser melting of the crystal lattice. We find that the experimentally observed dependence of SHG on crystal orientation remains unchanged up to the damage limit. Observed selection rules are analysed in terms of various possible contributions.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4889Keywords: oxidation ; surface alloys ; Fe-Cr alloys ; iron ; kineticsSource: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The oxidation behavior of several surface and bulk Fe-Cr alloys and iron at 300°C and 4×10−6 Torr oxygen was studied. The surface alloys were fabricated by implantation of 25 keV Cr ions into the outermost 300Å of polycrystalline iron samples. The oxide thickness as a function of oxygen exposure was obtained using proton-excited X-ray analysis, and composition profiles of oxide films were obtained using Auger electron spectroscopy and ion sputtering. The addition of Cr to Fe by surface and bulk alloying caused the oxidation rate to decrease and changed the oxidation kinetics from parabolic (for Fe) to logarithmic (for Cr concentrations ≥4.7at.%). Interpretation of the data in terms of simple oxidation theories indicates that the Cr additions may reduce the oxidation rate by altering the electronic properties of the metal-oxide interface.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4889Keywords: Oxidation ; iron ; kinetics ; sulfur ; surface analysisSource: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The growth of thin (0–200 Å) oxide films on iron at 200 and 300 °C has been studied as a function of time and oxygen partial pressure using proton-induced X-ray emission (PIXE) and Auger electron spectroscopy (AES). Oxidation was found to be initially retarded by sulfur which had segregated onto the iron surfaces during preoxidation annealing, but only if the iron surface contained the maximum or near-maximum sulfur coverage (ca. one-half monolayer). During and immediately following the oxygen-sulfur interaction, oxide buildup appeared to be limited by a surface reaction (adsorption, ionization, or dissociation). For most of the oxidation period, pressure-dependent logarithmic oxide growth was observed at 200°C, and pressure-independent parabolic oxide growth at 300°C. Interpretation of the data indicated that oxide growth at 200°C may be limited by quantum mechanical tunneling of electronic species through the previously formed oxide film, and oxide growth at 300°C may be limited by ionic diffusion through the previously formed oxide film. Comparison of AES and PIXE data indicated that the oxide films formed at 200°C were uniform in thickness over the surface of the metal, whereas films formed at 300°C had relatively thin areas where sulfur had remained.Type of Medium: Electronic ResourceURL:
