AbstractThe influence of high‐energy electron irradiation (Ee= 1.8 MeV) on the structure and the vibration properties of multi‐walled carbon nanotubes (MWCNTs) in a width range of absorption doses (3–10) MGy were investigated by means of X‐ray diffraction and Raman spectroscopy. It has been observed that the radiation promotes the weakness of the interlayer interactions as well as the damage of the cross‐linking along a radial direction, due to occurrence of the sp3‐hybridized states. The filling of polyvinyl chloride (PVC) by nanotubes, in low content (0.2 and 0.5 wt%), leads to an amplification of the microhardness. This can be attributed to the existence of donor‐acceptor interactions between polymeric macromolecules and nanotubes, which promotes a reduction of infringements in the conjugation chain of the polyene consistencies. However, the corresponding Raman spectrum cannot explain such enhancement of the microhardness.Der Einfluss von hochenergetischer Elektronenbestrahlung (Ee= 1.8 MeV) auf die Struktur und die Schwingungseigenschaften von Multiwalled Carbon Nanotubes (MWCNT) wurde untersucht. In einem breiten Spektrum der Absorptionsdosen (3–10 MGy) wurde der Einfluss durch Röntgendiffraktometrie und Ramanspektroskopie verfolgt. Es wurde beobachtet, dass der Bestrahlungsprozess zu einer Schwächung der Schichtwechselwirkung führt und zu einer Zerstörung der Vernetzung in der radialen Richtung durch das verstärkte Auftreten von sp3hybridisierten Zuständen. Die Füllung von Polyvinylchlorid (PVC) mit Carbon Nanotubes, mit einem niedrigen Füllungsgrad (0,2 und 0,5 Masse‐%) führt zu einer deutlichen Verstärkung der Mikrohärte. Diese Zunahme kann durch das Auftreten von Donor‐Akzeptor Wechselwirkungen zwischen den Polymermakromolekülen und den Nanotubes erklärt werden, da diese eine Verringerung der Störungen in den konjugierten Ketten der Polyene anregen. Die gemessenen Ramanspektren können eine solche Erhöhung der Mikrohärte allein nicht erklären.
Use of Ti in hard metal alloys – Part II: mechanical properties
Authors: Lamim J. D. , de Oliveira H. C. P , Batista A. C. , Guimarães R. S. , Filgueira M. 
Published: September 2010

AbstractWC‐Co hard metal is a material of high hardness, high compressive strength and wear resistance while maintaining good toughness and thermal stability. Samples of nanosized WC powders with 10 wt% Co, WC‐10 wt% Ti, WC‐9 wt% Ti‐1 wt% Co were cold pressed at 200 MPa and sintered at 1500°C during 1 hour under vacuum of 10–2 mbar. The characterization of the sintered materials was performed by the measurements of densification, HV30 hardness, fracture toughness and compression strength. The results showed that it is possible to process a hard metal through a Powder Metallurgical conventional route from nanoscaled WC grains, using Ti (or a Ti‐Co mixture) as a binder phase, with good mechanical properties.
SimCarb QuenchTemp – Ein neues Softwaremodul zur Simulation des Härteverlaufs beim Einsatzhärten
Authors: Gegner J. , Kaffenberger M. 
Published: September 2010

AbstractDie SimCarb‐Programmfolge bietet als leistungsfähige Stand‐Alone‐Lösung benutzungsfreundliche Windows‐Expertensoftware für die rechnergestützte Verfahrensauslegung des Einsatzhärtens in Forschung und industrieller Wärmebehandlung. Es wird ein neues Simulationswerkzeug zur Vorhersage der Tiefenverläufe von Abschreck‐ und Anlasshärte aus einem gegebenen Aufkohlungsprofil unter Berücksichtigung von Stahlzusammensetzung, Bauteilgeometrie und Prozessbedingungen vorgestellt. In der aktuellen Version setzt das Softwaremodul SimCarb QuenchTemp ein empirisches Modell um, dessen Grundlagen und technologischer Hintergrund ausführlich erläutert werden. Die Abschreckhärte wird durch Auswertung berechneter Jominy‐Kurvenscharen für die Kohlenstoffgehalte der Einsatzschicht am maßgeblichen Stirnflächenabstand abgeleitet. Der repräsentative Zylinderdurchmesser beschreibt den Werkstückeinfluss. Die Kühlwirkung des Mediums wird durch die Grossman'sche Abschreckintensität ausgedrückt. Die Bestimmung der Anlasshärte über Abminderungsfaktoren für Martensit beruht auf einer vereinfachten Gefügeanalyse. Umfangreiches Datenmaterial ist im Programm hinterlegt und in Bibliotheken verfügbar. Bedienung und praktische Anwendung der Software werden anhand von Screenshots und Simulationsbeispielen veranschaulicht.The SimCarb program suite as a powerful stand‐alone solution provides user‐friendly Windows expert software for computer‐aided case hardening engineering in research and industrial heat treatment. A new simulation tool is presented for the prediction of the depth distributions of the quenching and tempering hardness from a given carburization profile by taking into account the steel composition, component geometry, and process conditions. In the current version, the SimCarb QuenchTemp software module implements an empirical model, the basic principles and technological background of which are explained in detail. The quenching hardness is derived by evaluating calculated sets of Jominy curves for the carbon contents in the case at the applicable distance from the end face. The representative cylinder diameter characterizes the influence of the workpiece. The cooling ability of the medium is quantified by the Grossman quench severity. The determination of the tempering hardness by diminution factors for martensite is based on a simplified microstructure analysis. Large data sets are stored in the program and available in libraries. Operation and practical application of the software are illustrated by means of screenshots and simulation examples.
Influence of different pulse parameters on the deposition of Al2O3
Authors: Bobzin K. , Bagcivan N. , Ewering M. 
Published: September 2010

AbstractOxide PVD‐coatings like crystalline γ‐Al2O3 offer great potential for their use in cutting operations. They enable high resistance against abrasive wear, chemical inertness and high hot hardness. The pulsed Magnetron Sputter Ion Plating is a promising technique for applying oxide coatings onto cutting tools. The pulse duration and the duty cycle influence the stability of the deposition process. On the one hand pulse parameters can affect the ionization, on the other hand “target poisoning” and arcing can be reduced by choosing the right pulse values. In the present work the influence of different pulse parameters was investigated using optical emission spectroscopy (OES). It can be revealed that longer trev‐pulse times as well as lower duty cycles increase the aluminum ion density. With the chosen pulse parameters different coatings were deposited. The analysis was done using common thin film test equipment such as calo‐test, nanoindentation or scratch test. The results show that an increasing pulse frequency decreases the hardness, but improves adhesion of the coating.Oxidische PVD‐Schichten wie kristallines Al2O3 versprechen großes Potenzial für die Anwendung in der Zerspanung. Sie ermöglichen eine hohe Beständigkeit gegen abrasiven Verschleiß, chemische Inertheit und ein hohe Warmhärte. Das gepulste Magnetron Sputter Ion Plating Verfahren ist eine viel versprechende Technik zur Abscheidung oxidischer Schichten auf Zerspanwerkzeuge. Zum einen können die Pulsparameter die Ionisation beeinflussen, zum anderen können “Targetvergiftung” und “Arcing” durch die Wahl der richtigen Pulsparameter reduziert werden. In der vorliegenden Arbeit wurde der Einfluss unterschiedlicher Pulsparameter mit Hilfe von optischer Emissionsspektroskopie untersucht. Es kann gezeigt werden, dass längere trev‐Zeiten sowie geringere Tastverhältnisse die Aluminiumionendichte erhöhen. Mit ausgewählten Pulsparametern wurden anschließend Schichten abgeschieden und mit Hilfe verschiedener Analysemethoden wie Nanoindentation zur Ermittlung der mechanischen Eigenschaften oder Scratchtest untersucht.
A probability and decision‐model analysis of PROVOST seasonal multi‐model ensemble integrations
Authors: Palmer T. N. , Branković Č , Richardson D. S. 
Published: September 2010

AbstractA probabilistic analysis is made of seasonal ensemble integrations from the PROVOST project (PRediction Of climate Variations On Seasonal to interannual Time‐scales), with emphasis on the Brier score and related Murphy decomposition, and the relative operating characteristic. To illustrate the significance of these results to potential users, results from the analysis of the relative operating characteristic are input to a simple decision model. The decision‐model analysis is used to define a user‐specific objective measure of the economic value of seasonal forecasts. The analysis is made for two simple meteorological forecast conditions or ‘events’, E, based on 850 hPa temperature. The ensemble integrations result from integrating four different models over the period 1979–93. For each model a set of 9‐member ensembles is generated by running from consecutive analyses.Results from the Brier skill score analysis taken over all northern hemisphere grid points indicate that, whilst the skill of individual‐model ensembles is only marginally higher than a probabilistic forecast of climatological frequencies, the multi‐model ensemble is substantially more skilful than climatology. Both reliability and resolution are better for the multi‐model ensemble than for the individual‐model ensembles. This improvement arises both from the use of different models in the ensemble, and from the enhanced ensemble size obtained by combining individual‐model ensembles; the latter reason was found to be the more important. Brier skill scores are higher for years in which there were moderate or strong El Niño Southern Oscillation (ENSO) events. Over Europe, only the multi‐model ensembles showed skill over climatology. Similar conclusions are reached from an analysis of the relative operating characteristic.Results from the decision‐model analysis show that the economic value of seasonal forecasts is strongly dependent on the cost, C, to the user of taking precautionary action against E, in relation to the potential loss, L, if precautionary action is not taken and E occurs. However, based on the multi‐model ensemble data, the economic value can be as much as 50% of the value of a hypothetical perfect deterministic forecast. For the hemisphere as a whole, value is enhanced by restriction to ENSO years. It is shown that there is potential economic value in seasonal forecasts for European users. However, the impact of ENSO on economic value over Europe is mixed; value is enhanced by El Niño only for some potential users with specific C/L.The techniques developed are applicable to complex E for arbitrary regions. Hence these techniques are proposed as the basis of an objective probabilistic and decision‐model evaluation of operational seasonal ensemble forecasts.
