For fifteen years Prof. I. Müller and his team have worked on different aspects of shape memory: statistical mechanical models; modelling of material properties; thermodynamics; experimental work, such as production of single crystals of CuAlNi and CuZnAl, stress-strain-temperature measurements and the construction of a prototype shape-memory engine. The main focus of this team within the network activity is the simulation of shape-memory alloys and their application to the real-time adjustment of an airfoil to changing conditions of the incoming airstream. In this project a model of a flexible wing which adjusts its shape in real time to changing flight conditions is to be built and tested.

Two doctoral and two post-doctoral one-year positions will be filled; the research programmes envisaged by this team include topics such as thermomechanics and statistical mechanics, numerical methods for the solutions of PDE's, and theory and/or practice of optimal control theory.

Applicants should therefore have an interest and background in thermomechanics and in these disciplines.

TEAM 8: University of Antwerp, RUCA, Belgium.

Coordinator:	Prof. Dominique Schryvers, Electron-Microscopy for Materials Research, University of Antwerp, RUCA
Team members:	D Schryvers, L. Rossou, J.-W. Seo, J. Van Landuyt, G. Van Tendeloo, M. Yandouzi (EMAT, RUCA).
Contact:	Prof. D. Schryvers Electron-Microscopy for Materials Research Groenenborgerlaan 171 University of Antwerp, RUCA B-2020 Antwerp Belgium Tel +32-3-2180247 Fax +32-3-2180257 email schryver@ruca.ua.ac.be
Team web site:	http://www.ruca.ua.ac.be/emat

This team is part of the Electron Microscopy for Materials Science (EMAT) facility of the University of Antwerp. The group currently has six different electron microscopes available dedicated to different modes (HRTEM, HVEM, diffraction, EDX, EELS) and works on a variety of materials science and physics topics such as alloys, ceramics, nanotubes, superconductors, semiconductors, imaging theory, electron holography, etc..

Within this TMR programme we're looking for post-doc researchers with the following experience:

1) specialised in thin film preparation with some basic knowledge of electron microscopy. The idea is that the experience of the post-doc would help in extending the thin film productions currently being started in the lab. During his stay the post-doc will acquire experience in the available EM characterisation techniques, or

2) specialised in EM in general with emphasis on the study of microstructures and phase transformations.

In both cases the post-doc researchers would work within the area of phase transformations in alloys with emphasis on martensitic transformations. Current projects include nanoscale thin films of Ni-Al and Ni-Mn, displacive and diffusive transformations in NiMnTi, splat-cooled and melt-spun Ni-Al structure determination in NiTi, CuZr, precursor phenomena in general.

The preferred timing would be a term of one year starting January 1,1999. Other suggestions are also welcome.
