Das Non Vacuum Electron Beam Welding (NV-EBW) hat zahlreiche Vorteile im Vergleich zum Elektronenstrahlschweißen im Vakuum, da man unter normalem Atmosph{\"a}rendruck arbeiten kann. Im Hinblick auf die reproduzierbare Qualit{\"a}t, insbesondere im Bereich der Massen-Fertigung, ist die Kontrolle der Strahlparameter sowie deren Einfluss auf das Schweißergebnis von großer Bedeutung. Durch eine genaue Kenntnis der Strahlkenngr{\"o}ßen wie des Strahldurchmessers und der Leistungsdichteverteilung kann eine Aussage {\"u}ber die sich ausbildende Schweißnaht sowie die Schweißbaddynamik getroffen werden. Messungen der Strahlkenngr{\"o}ßen im Prozess erlauben insbesondere die Untersuchung von Humping-Effekten. In diesem Beitrag wird der Prozess der Elektronenstrahlvermessung unter atmosph{\"a}rischen Bedingungen beschrieben. Es wird zudem die Abh{\"a}ngigkeit der Elektronenstrahlcharakteristika von den verschiedenen Prozessparametern dargestellt.}, language = {de} } @article{MukherjeePrahlBlecketal.2010, author = {Mukherjee, Krishnendu and Prahl, Ulrich and Bleck, Wolfgang and Reisgen, Uwe and Schleser, Markus and Abdurakhmanov, Aydemir}, title = {Characterization and modelling techniques for gas metal arc welding of DP 600 sheet steels}, series = {Materialwissenschaft und Werkstofftechnik}, volume = {41}, journal = {Materialwissenschaft und Werkstofftechnik}, number = {11}, publisher = {Wiley-VCH}, address = {Weinheim}, issn = {1521-4052}, doi = {10.1002/mawe.201000692}, pages = {972 -- 983}, year = {2010}, abstract = {The objectives of the present work are to characterize the Gas Metal Arc Welding process of DP 600 sheet steel and to summarize the modelling techniques. The time-temperature evolution during the welding cycle was measured experimentally and modelled with the softwaretool SimWeld. To model the phase transformations during the welding cycle dilatometer tests were done to quantify the parameters for phase field modelling by MICRESS®. The important input parameters are interface mobility, nucleation density, etc. A contribution was made to include austenite to bainite transformation in MICRESS®. This is useful to predict the microstructure in the fast cooling segments. The phase transformation model is capable to predict the microstructure along the heating and cooling cycles of welding. Tensile tests have shown the evidence of failure at the heat affected zone, which has the ferrite-tempered martensite microstructure.}, language = {en} } @article{ReisgenSchleserMokrovetal.2010, author = {Reisgen, Uwe and Schleser, Markus and Mokrov, Oleg and Ahmed, Essam}, title = {Shielding gas influences on laser weldability of tailored blanks of advanced automotive steels}, series = {Applied surface science}, volume = {257}, journal = {Applied surface science}, number = {5}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0169-4332 (E-Journal); 0169-4332 (Print)}, doi = {10.1016/j.apsusc.2010.08.042}, pages = {1401 -- 1406}, year = {2010}, abstract = {The effects of shielding gas types and flow rates on CO2 laser weldability of DP600/TRIP700 steel sheets were studied in this work. The evaluated shielding gases were helium (He), argon (Ar) and different mixtures of He and Ar. Weld penetration, tensile strength and formability (Erichsen test) of laser welds were found to be strongly dependent upon the shielding gas types. The ability of shielding gas in removing plasma plume and thus increasing weld penetration is believed to be closely related to ionization potential and atomic weight which determine the period of plasma formation and disappearance. It was found that the higher helium shielding gas flow rate, the deeper weld penetration and the lower weld width.}, language = {en} } @article{AhmedReisgenSchleseretal.2010, author = {Ahmed, Essam and Reisgen, Uwe and Schleser, Markus and Mokrov, Oleg}, title = {On formability of tailor laser welded blanks of DP/TRIP steel sheets}, series = {Science and technology of welding and joining}, volume = {15}, journal = {Science and technology of welding and joining}, number = {5}, publisher = {Maney}, address = {Leeds}, issn = {1743-2936}, doi = {10.1179/136217110X12731414739754}, pages = {337 -- 342}, year = {2010}, abstract = {This paper aims to evaluate the formability of tailor welded blanks of dual phase (DP600)/transformation induced plasticity (TRIP700) steel sheets. In this work, bead on plate butt joints of 2·5 mm DP600 and 1·2 mm TRIP700 steel sheets were performed using CO2 laser beam welding. Microhardness measurements and transverse tensile testing were carried out to characterise the welds. The formability of base metals and welds were investigated by standard Erichsen test. In a perpendicular tensile test to the weld line, all specimens were fractured at the TRIP base metal, and the strengths were somewhat higher than those of base metal. There was a significant reduction in formability caused by welding of the DP600/TRIP700 steel sheets, and the formability increased with increasing welding speed.}, language = {en} } @article{HaselgruberMautnerThiele2010, author = {Haselgruber, Nikolaus and Mautner, Karin and Thiele, Jan}, title = {Usage Space Analysis for Reliability Testing}, series = {Quality and Reliability Engineering International}, volume = {26}, journal = {Quality and Reliability Engineering International}, number = {8}, publisher = {Wiley}, address = {New York}, issn = {1099-1638}, doi = {10.1002/qre.1155}, pages = {877 -- 885}, year = {2010}, abstract = {During the development process of a complex technical product, one widely used and important technique is accelerated testing where the applied stress on a component is chosen to exceed the reference stress, i.e. the stress encountered in field operation, in order to reduce the time to failure. For that, the reference stress has to be known. Since a complex technical product may fail regarding numerous failure modes, stress in general is highly dimensional rather than scalar. In addition, customers use their products individually, i.e. field operation should be described by a distribution rather than by one scalar stress value. In this paper, a way to span the customer usage space is shown. It allows the identification of worst case reference stress profiles in significantly reduced dimensions with minimal loss of information. The application example shows that even for a complex product like a combustion engine, stress information can be compressed significantly. With low measurement effort it turned out that only three reference stress cycles were sufficient to cover a broad range of customer stress variety.}, language = {en} } @article{EnningBaier2009, author = {Enning, Manfred and Baier, M.}, title = {Energetic and operational use of FlexCargoRail freight wagons in the single wagon load traffic / Baier, M. ; Enning, M.}, series = {Towards zero emission : EVS 24, the 24th International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium \& Exhibition, Stavanger, Norway, May 13 - 16, 2009 ; symposium proceedings / organised by AVERE ...
