Professional biography

Hedieh completed her PhD on recrystallization of highly deformed aluminium alloys at the University of Manchester in 2003. Subsequently she worked as a PDRA for two years at the University of Manchester where she studied the effect of initial grain size on microstructural development during cold rolling deformation of a single-phase aluminium alloy and also the dynamic grain growth in a single-phase aluminium alloy after deformation by plane strain compression at low temperature and different strain rates.

In 2005 she joined Oxford Instruments Analytical plc (Nanoanalysis sector) as an Application Specialist. In 2010 she returned to academia at the Open University as a Research Fellow.  

Research interests

Hedieh's research interests are mainly around material characterisation in particular creep damage assessment in order to extend life of engineering components in safety critical applications. This involves using in-house characterisation techniques such as SEM, EBSD and EDX. Also accessing central neutron facilities such as ISIS, ILL and HZB to perform Small Angle Neutron Scattering (SANS) experiments.

The Physics and Mechanics of Creep Cavity Nucleation and Sintering in Energy Materials

Co-investigator01 Oct 201830 Jun 2022EPSRC Engineering and Physical Sciences Research Council

The research project will study the physics and mechanics of creep cavity nucleation and the reverse process of healing by sintering in polycrystalline materials for energy applications using both modelling and experimental approaches. The experimental work will focus on a model single phase material (high purity copper), a simple particle strengthened material (Type 316L stainless steel), a more complex austenitic stainless steel (Type 316H) and a superalloy (IN718). An array of state-of-the-art experimental techniques will be applied to inform the development of new physics-based cavity nucleation and sintering models for precipitation hardening materials. Once implemented in mechanical analyses, and validated, such models will form the basis for development of improved lifetime assessment procedures for high thermal efficiency power plant components.
