Experiments have been performed on sodium, potassium, and silver particles supported on a LiF(100) single-crystal surface under ultrahigh vacuum conditions. Measurements include the determination of the desorption rate as a function of laser wavelength, laser intensity, average particle size, and substrate temperature, the determination of the kinetic energy of the desorbed atoms, the investigation of the optical spectra of the supported metal particles, and the study of the influence of adsorbate molecules on the desorption rate. Furthermore, theoretical extinction and absorption spectra of the metal particles have been calculated with the classical electrodynamical Mie theory as a function of average particle size and excitation wavelength. Also, the radial electric field at the particle surface was computed. The results of the experiments and theoretical calculations are combined to give a consistent picture of the mechanism of metal-atom desorption by electronic excitation with laser light. A realistic surface potential from which the atoms escape and nonlocal optical effects are taken into account. The latter introduce additional absorption channels by the formation of electron-hole pairs in the surface layer of the particle which relax into antibonding states before desorption occurs. Finally, the mechanism is discussed in the light of similar phenomena observed for thin metal films. Possibilities for future work are outlined. © 1993 The American Physical Society}, language = {en} } @article{GoetzHoheiselTraegeretal.1993, author = {G{\"o}tz, T. and Hoheisel, W. and Tr{\"a}ger, F. and Vollmer, Michael}, title = {Interplay between collective and single electron excitations in large metal clusters}, series = {In: Zeitschrift f{\"u}r Physik / D 26 (1993), 267-269}, journal = {In: Zeitschrift f{\"u}r Physik / D 26 (1993), 267-269}, year = {1993}, language = {en} } @incollection{VollmerKreibig1992, author = {Vollmer, Michael and Kreibig, U.}, title = {Collective excitations of large metal clusters}, series = {In: Nuclear physics concepts in the study of atomic cluster physics : proceedings of the 88th W.-E.-Heraeus-Seminar, held at Bad Honnef, FRG, 26 - 29 November 1991 / R.

Rays are created in the laboratory with parallel light beams that pass through artificial fogs and milk-water solutions. Light scattered by 90° in a dilute mixture of whole milk first increases in intensity with distance from the source to a maximum as a result of multiple scattering by mainly small angles before decreasing exponentially due to extinction as distance continues to increase. Crepuscular rays are simulated for three cloud configurations. In case 1, the Sun at the zenith is blocked by a cloud with an overhanging anvil. The rays appear white against blue sky and are brightest when atmospheric turbidity, β≈11 . Shading by the anvil separates maximum brightness from apparent cloud edge. In case 2, a ray passes through a rectangular gap in a cloud layer. The ray is faint blue in a molecular atmosphere but turns pale yellow as β and solar zenith angle, ϕsun , increase. At ϕsun=60° it appears most striking when the cloud is optically thick, β≈5 , and the beam width Δx≈1000 m . In these cases, increasing aerosol radius, raer , to about 1000 nm brightens, narrows, and shortens rays. In case 3, the twilight Sun is shaded by a towering cloud or mountain. The shaded rays are deeper blue than the sunlit sky because the light originates higher in the atmosphere, where short waves have suffered less depletion from scattering. The long optical path taken by sunlight at twilight makes color and lighting contrasts of the rays greatest when the air is quite clean, i.e., for β-1≪1 .

According to conventional assumptions the surface of aluminium workpieces is cleaned during EP but the tungsten electrode is more heated due to electron work function. During EN the tungsten electrode cools down and the workpiece is melted. Therefore, optimal settings of the power source mostly aim for maximal penetration and minimal electrode wear. This paper presents a study of arc attachments in TIG welding on aluminium. Two different arc attachments to the cathodic workpiece could be attested with only one of them actually cleaning the surface. The first one is a spot mode (highly dynamic) that attaches to the edges of oxide layers and cracks them. The second one is also a spot mode, but it attaches to weld pools. It does not clean the surface but heats the base material intensively. Both arc attachment modes compete against each other. As a result, the cleaning area narrows with wider weld pools due to an increasing attachment to the weld pool during EP. The influences on the arc attachment to the aluminium cathode as well as the contradictions in present literature are discussed. Possible adjustments of the AC balance for optimized processes are proposed.}, language = {en} } @article{WildenJahnMelahinetal.2010, author = {Wilden, J. and Jahn, S. and Melahin, N. and Rehfeldt, L. and Luhn, T. and Goecke, Sven-Frithjof and Schmid, E. and Berger, U.}, title = {Brazing as the key to resource-efficient and energy-efficient joining in the product life cycle}, series = {In: Welding and cutting (2010) 5, 301-312}, journal = {In: Welding and cutting (2010) 5, 301-312}, issn = {1612-3433}, pages = {301 -- 312}, year = {2010}, language = {en} } @article{WildenJahnMilahinetal.2010, author = {Wilden, J. and Jahn, S. and Milahin, N. and Luhn, T. and Rehfeldt, L. and Goecke, Sven-Frithjof and Schmid, E. and Berger, U.}, title = {Perspektiven und Visionen zum Schweissen moderner Stahlwerkstoffe}, series = {In: Stahl und Eisen 130 (2010) 10, S. 71-75}, journal = {In: Stahl und Eisen 130 (2010) 10, S. 71-75}, issn = {0340-4803}, pages = {71 -- 75}, year = {2010}, language = {de} } @article{GhoshDornGoecke2001, author = {Ghosh, P.

This way, damage to galvanized coating, for example in the case of steels, could be avoided or significantly reduced. Damage to the galvanized coating represents an outwardly visible phenomenon that can have a negative impact on the component's corrosion resistance. On the other hand, from the metallurgical viewpoint, controlling heat input represents an important way to solve the problems associated with heat joining of metals with incomplete solid-state solubility. The formation of fragile intermetallic phases during cooling, for example, occurs with aluminium/steel or aluminium/titanium. The process and the correct choice of filler materials are key points for the success of the joining method. In the case of the combination of aluminium and steel, zinc represents a suitable filler material, for example for brazing. The melting temperature is around 420°C and the wettability, with regard to galvanized steel, is favoured by the zinc layer, while on the aluminium part, it is possible to avoid the use of flux, thanks to the activating action of the voltaic arc. However, the low melting and vaporization temperatures of zinc make even 'short arc' processing rather difficult. Only new developments in electrical sources for welding, and in particular new processes, offer the possibility of reducing the heat input by modifying the 'short arc' process. The difficulties described are also valid for the combination of titanium and aluminium, and are associated with the formation of phases such as Ti x A1 y . Again in this case, this paper will present a strategy for joining sheets less than 2 mm thick. In the past years, an increasing number of strategies to join zinc-coated steels can be observed. Brazing represents a profitable way to join zinc-coated steels at low temperatures, reducing or avoiding zinc evaporation. In order to completely avoid damaging zinc coating, the set of ZnAl-f{\`i}llers was already investigated for laser brazing of zinc-coated steels as well as for joining steel with aluminium. Furthermore, thanks to new developments in arc wire technology, ZnAl-electrodes can be used for MIG-brazing as well. In this case, the conventional short arc, which normally does not allow brazing with zinc wires as eruption-like evaporation occurs, is modified and controlled. The drop formation on the wire tip, the metal transfer, and the heat input can be controlled and modified very precisely, so that processing of filler material can be performed easily for thin sheets (till 0.8-1.5 mm) and at low-processing speed, below 0.3-0.4 m/min. The control of the heat input occurs due to abruptly reducing the current after short arc. The disadvantages connected with a lower heat input in the base material are a restricted wetting behaviour of the zinc pool on the base material and the low-brazing speed due to a very high cooling rate. The focus of the presented investigation is the development of strategies, in order to enhance process conditions for brazing sheets of zinc-coated steels and aluminium.}, language = {en} } @inproceedings{GoeckeWildenJahnetal.2008, author = {Goecke, Sven-Frithjof and Wilden, J. and Jahn, S. and Reich, S. and Fedtke, A. and Vollertsen, F. and Thomy, C.}, title = {Technologiekette zum Produzieren, Reparieren und Recyceln von Produkten in Material-Mix-Bauweise - PROREMIX}, series = {In: Die Verbindungs-Spezialisten 2008 : Vortr{\"a}ge und Posterbeitr{\"a}ge der Veranstaltung in Dresden vom 17. bis 19.

Aktuelle Entwicklungen von Lotwerkstoffen zielen sowohl in Richtung Absenkung der Schmelztemperaturen als auch in Richtung Festigkeitssteigerung, um die Anwendungsm{\"o}glichkeiten noch weiter zu vervielf{\"a}ltigen. Dabei unterliegen sowohl Eisenbasislegierungen als auch Systeme auf Kupfer- oder Zinkbasis einer stetigen Weiterentwicklung. Die bereits heute erreichbaren Festigkeiten reichen bis etwa 900 MPa (CuAl8Mn13Ni2Fe2) bei Kupferbasislegierungen und 410 MPa (AnAl7,5Cu2,5 + 180 ppm Mg) bei Zinklegierungen. Neben der Energieeinsparung durch die reduzierten Prozesstemperaturen beim F{\"u}gen und der M{\"o}glichkeit Hybridstrukturen herzustellen, ergeben sich außerdem Vorteile bei der Reparatur und dem Recycling von Bauteilen. Da der Zusatzwerkstoff unabh{\"a}ngig vom Grundwerkstoff wiederaufgeschmolzen werden kann, sind eine leichtere Reparatur und auch ein Trennen der Bauteile zum Recycling m{\"o}glich. Dies f{\"u}hrt bei Betrachtung des gesamten Produktlebenszyklus zu einer h{\"o}heren Energieeffizienz und einer Schonung der nat{\"u}rlichen Rohstoffe und Ressourcen. Durch die steigenden Energie- und Werkstoffkosten und den damit verbundenen Kostendruck r{\"u}ckt dieser Aspekt neben der Machbarkeit und Produktivit{\"a}t langsam, aber sicher ins Blickfeld der Unternehmen. Kostenvorteile ergeben sich außerdem durch Betrachtung und Modifikation ganzer Fertigungsketten. Niedrigschmelzende Zusatzwerkstoffe erm{\"o}glichen beispielsweise das F{\"u}gen verzinkter Halbzeuge ohne Zinkschichtverletzung. Da Halbzeuge in großen Mengen kosteng{\"u}nstiger verzinkt werden k{\"o}nnen als fertige Konstruktionen, ist das F{\"u}gen verzinkter Halbzeuge insgesamt g{\"u}nstiger als das Verzinken geschweißter Stahlkonstruktionen.}, language = {de} } @inproceedings{Goecke2005, author = {Goecke, Sven-Frithjof}, title = {Energiereduziertes Lichtbogen-F{\"u}geverfahren f{\"u}r w{\"a}rmeempfindliche Werkstoffe}, series = {In: Schweißen und Schneiden 2005 : Vortr{\"a}ge der gleichnamigen Großen Schweißtechnischen Tagung in Essen vom 12. bis 14.

These can have devastating and long-lasting effects on the industry. Despite the advances being made in railway permanent way engineering, inspection and rail-making technology, continually increasing service demands have resulted in rail failure continuing to be a substantial economic burden and a threat to the safe operation of virtually every railway in the world.
