Netherlands: PhD researcher in engineering

Font size: Decrease font Enlarge font

The research project concerns the development
and exploration of a new manufacturing technique to clad and/or alloy
materials, in particular advanced aircraft grade aluminums. Cladding
and alloying is performed in the solid state employing a modified
Friction Stir Welding (FSW) technique; filler material is supplied
during welding through a specially developed hollow tool.

The research aims at a thorough understanding of the relation
between the properties of the clad layer / local alloyed material and
the process parameters of the modified FSW technique. An important part
of the project is the modeling and experimental verification of the (i)
materials changes inside and outside of the weld area, (ii) the flow of
filler material from the modified FSW tool to the work piece and (iii)
the local cladding and/or alloying of the work piece. Advanced finite
element modeling employing an arbitrary Lagrange Eulerian approach is
carried out to determine the local material flow and temperature fields
and capture the mixing of filler material within the work piece.

The experimentally validated and verified models are used to
predict the FSW process conditions for optimal material properties for
a series of aircraft specific applications, such as the deposition of a
thin, protective Al clad layer on top of a 2xxx or 7xxx alloy. The
accordingly manufactured demonstration materials are tested under
aircraft specific conditions on corrosion and fatigue properties.

A special filler supply system and modified FSW tools are designed
and manufactured as part of the research, since such a system does not
exist at present.


The PhD researcher candidate should:

•hold a Master’s degree in Mechanical Engineering, Materials Science or a related field;

•have a good background in numerical modeling with emphasis on modeling the mechanical behaviour of materials;

•have affinity with materials science and should have hands-on experience with experimental work;

•have strong written and oral communication skills in English.

The vacancy is located at Delft University of Technology in Delft.
