Ph.D. student position at the Institute for Metallic Materials- Effect of hydrogen on mechanical properties of BMG’s -Bulk Metallic Glasses (BMG’s) represent a novel class of metallic materials with unique properties. They exhibit excellent mechanical performance data, which highly recommend them as new materials for structural applications, sportive goods, precision mechanical elements etc. Due to their short-range ordered atomic structure and multicomponent composition bulk glass-forming alloys exhibit also very interesting electrochemical properties, e.g. a high reactivity for cathodic hydrogen absorption. So far studies on the interaction of electrochemical and mechanical loading of BMG’s are still rather scarce.
The IFW Dresden is a highly recognized research institute in the field of metastable alloys. Our research program comprises their preparation by non-equilibrium techniques, their structural, physical and chemical characterization and their transfer to industrial applications. The group "Electrochemical Properties of Functional Materials" of the Institute for Metallic Materials has a long-term expertise in studying corrosion and hydrogenation processes of amorphous and nanostructured alloys.
In the framework of a network- project funded by the Leibniz-Association the group is looking for a Ph.D. student for the study of effects of hydrogen on the mechanical properties of bulk metallic glasses. The task involves the preparation of selected alloys by casting or rapid quenching, the electrochemical hydrogenation treatment and hydrogen analysis, the mechanical testing on the macro- and nano-scale and the attendant structural, thermal and surface-analytical characterization.
Successful applicants should hold a Diploma or Master degree in materials science, chemistry or physics or related sciences. A profound knowledge in physical properties of metallic materials and relevant characterization methods as well as in principles and methods of electrochemistry is required. Capability for teamwork and co-operation with the local researchers and international research groups and a good knowledge of English is needed. We are offering excellent working conditions and facilities in an active multidisciplinary research environment.
The position is limited for 3 years Starting date is : January 2008 (or earlier)
We are looking for ambitious, creative women who aim for a successful
independent career towards full professorship in a European top research
university. Successful candidates will be expected to establish an independent,
externally funded research program in collaboration with colleagues at our
university and elsewhere. They will also be expected to participate in and
contribute to the development of the teaching programme of the Faculty. RF
Fellowships are funded with a generous startup package, worth around 200,000
euro. APPLICANTS
SHOULD SUBMIT: 3. a 3-5 page statement of research accomplishments and future research goals 4. 3

Post
doc. position Development
of new transmission electron microscopy techniques ¾ 3DTEM Job description
This project
aims at developing unique TEM techniques for 3D characterization of
nanocrystalline materials. The technique development relies on the TEM basic
functions of electron diffraction and imaging, but involves various challenges
such as indexing of multiple electron diffraction patterns, dynamic effect of
electron diffraction, electron nanodiffraction, sample tilting effect, 3D
reconstruction and computer programming. Three related techniques will be
developed, providing both crystallographic and spatial information of the
structure: (1) 3D analysis of dislocation configuration in low angle boundaries,
(2) Mapping of grain boundary planes and (3) 3D mapping of nanocrystalline
grains. The project has been inspired from the success of development of 3D
X-ray diffraction microscope and nanoscope. The techniques developed will be
applied to characterize deformed and recovered nanocrystalline materials. Qualifications
