Nickel-Aluminium-Nanokomposit wurde durch ein konventionelles pulvermetallurgisches Verfahren mit Hilfe einer direkten Reaktion von Aluminiumpulver und Nickelchlorid entwickelt, um seine mechanischen Eigenschaften zu bestimmen. Bei Raumtemperatur bildete der Verbundwerkstoff zunächst Al-Ni und nach Erhitzen auf 600ºC bildet das Verbundpulver Al3Ni und AlNi. Während der Vermischung von feinem Al-Pulver und Ni-Chloridlösung kam es zu einer großen exothermen Reaktion, was durch das Vorhandensein eines großen exothermen Peaks in der Differentialthermoanalysekurve bestätigt wird. Zu Beginn...

Un nanocomposite Nickel-Aluminium a été développé par un procédé conventionnel de métallurgie des poudres à l'aide de la réaction directe de la poudre d'aluminium et du chlorure de nickel pour déterminer ses propriétés mécaniques. A température ambiante, le composite était initialement sous forme de Al-Ni et après chauffage à 600ºC, la poudre composite forme Al3Ni et AlNi. Pendant le mélange de la poudre fine d'aluminium et de la solution de chlorure de nickel, une réaction exothermique importante s'est produite et le résultat est confirmé par la présence d'un pic...

The latest in parallel EM solutions with both in-core and out-of-core solvers

The solution of complex electromagnetic (EM) problems requires one to address the issues related with numerical accuracy and efficient distribution of the solution procedure over multiple computational nodes. With the advent of multicore processors and high performance computing (HPC) technology, the EM software designers need to know how to add new functionality to computational EM codes so that they can run efficiently on these new processors.
