英国剑桥大学材料科学博士后职位

Applications are invited for a three-year post-doctoral research associate position in the modelling of plasticity in hydrogen embrittlement resistant ultra-strong steels. The work will focus on describing the deformation response of novel ultra-strong steels for bearing, aerospace and automotive applications. Thermostatistical modelling of plasticity will be combined with the description of a variety of deformation mechanisms to design novel alloying systems; the designed alloys are expected to display extreme hardness whilst preventing hydrogen embrittlement. Several microstructural scenarios will be considered, including high-carbon martensitic and bainitic systems, mid-carbon alloys, nanostructured carbide-free steels and twinning and transformation induced plasticity systems.

The successful candidate should demonstrate experience in modelling plasticity employing thermostatistical and statistical mechanics concepts. He/she should display a thorough understanding of steel mechanical metallurgy, and some experience on nickel (super)alloys. Understanding of the interactions of carbides, twins, retained austenite, ferrite and intermetallic phases with each other under deformation is expected. Moreover, she/he should be able to co-ordinate the production and testing of alloys, and to interact with PhD students as part of a larger research programme.

The work will be performed within the framework of the SKF University Technology Centre at the University of Cambridge, under the sponsorship of the Engineering and Physical Sciences Research Council of the United Kingdom, and under the supervision of Dr. Pedro Rivera.

Exceptional individuals with a PhD, ScD or equivalent degree in Materials Science, Metallurgy, Physics or similar subject are encouraged to apply. The ideal candidate should hold a strong publication record. The position is expected to be filled as soon as possible for commencement in November 2014. Enquiries pertaining to the scientific nature of the work shall be addressed to Dr. Pedro Rivera (pejr2@cam.ac.uk).
