Dr Peng Gong – Postdoctoral Research Associate, Materials Science & Engineering

PhD Physics, The University of Sheffield (2016)

My research involves the microstructural evolution and the subsequent development of mechanical properties, during the thermomechanical processing and heat treatment of various kind of steels.

I have been working as a Postdoctoral Research Associate on the DARE programme since June 2016, focusing on the development of higher strength resource efficient steels for lighter road vehicles.

 

Dr Junheng Gao – Postdoctoral Research Associate, Materials Science & Engineering

BEng Materials Science and Engineering, University of Zhengzhou, China (2008)

PhD in Materials Science, University of Sheffield (2015)

My research interests are in the composition and microstructure design to obtain high strength and decent ductility in metastable beta titanium alloy based on relatively cheap alloying elements.

I have been working as a Postdoctoral Research Associate on the DARE programme since April 2015 and my research focuses on the theme “Beta Titanium Alloys for Resource Efficiency”.

 

Dr Dikai Guan – Postdoctoral Research Associate, Materials Science & Engineering

BSc Materials Science, Central South University, China (2008)

MSc Materials Science, Central South University, China (2011)

PhD Materials Science, University of Sheffield (2016)

I commenced as a Postdoctoral Research Associate on the DARE programme in April 2015; my research focuses on the theme “Magnesium (Mg) Alloys that are less dependent on Rare Earths”.

My work revolves around the understanding of how Rare Earth elements work in Mg alloys and finding replacement elements which will produce weak basal texture Mg alloys that are cost and resource efficient.

 

Dr Oliver Hatt – Postdoctoral Research Associate, Materials Science & Engineering

After obtaining a First Class degree in Chemistry, I initially followed a mechanical engineering career working for the Advanced Manufacturing Research Centre, Sheffield and Boeing, before studying for my PhD at the University of Sheffield.

My research is centred on titanium (Ti) alloy machining, particularly the interactions at the tool workpiece interface, which is underpinned by alloy and tool design.

Within the DARE Programme I am looking at the development of more machinable titanium alloys, without compromising titanium’s excellent mechanical properties.

Dr Lefteri Andritsos – Postdoctoral Research Associate

BSc Materials Science, University of Patras (2011)

PhD Physics, Queen Mary University of London (2015)

My scientific interests are in atomic properties of materials and the way the atomic structure and dynamics affect material properties and behaviour. I use atomistic simulations and neutron scattering techniques to study various properties of materials within and beyond experimental limitations.

I commenced as a Postdoctoral Research Associate for the DARE programme in May 2015 and my research is linked to the theme “Magnesium (Mg) Alloys that are less dependent on Rare Earths”.  My work includes the study of the structural and mechanical properties of magnesium and magnesium alloys and the understanding of atomic dynamics between solids and the corresponding liquids. Using the results from my research we aim to predict how alternatives to Rare Earth elements will work in Mg alloys.           

 

Guy Skinner – PhD Student

MSci Theoretical Physics, University College London (2015)

A PhD student at Kings College since October 2015, my research interests lie in the physics of metals, alloys and intermetallic compounds and are linked to the DARE research theme “Magnesium Alloys less dependent on Rare Earths”.

I use a variety of atomistic and electronic structure methods to determine the structural and mechanical properties of metal alloys. At present, I am working towards an understanding of the origin of the plastic anisotropy in magnesium and its alloys.

Dr Zebang Zheng – Postdoctoral Research Associate, Department of Materials

B.Eng. in Materials Science and Engineering, Northwestern Polytechnical University (2008-2012)

M.Sc. in Materials Science and Engineering, Imperial College London (2012-2013)

Ph.D. in Materials Science and Engineering, Imperial College London (2014-2016)

A Postdoctoral Research Associate on the DARE Programme since February 2017, I am involved in the research theme “Magnesium Alloys less dependent on Rare Earths”.   My research focuses on understanding twin nucleation in magnesium alloys using modelling techniques, with the aim of developing a twin nucleation criterion that can be used to predict twinning under deformation.

 

Chaitanya Paramatmuni – PhD student, Department of Materials

B.E. Mechanical Engineering, Visvesvaraya Technological University, India (2012)

M.S. Metallurgical and Material Science Engineering, Indian Institute of Technology-Madras, India (2016)

My research interests are based on integrated modelling and experimental approaches that provide insights into micro-mechanics of materials. I am currently working on strain-rate sensitivity, stress relaxation and twin nucleation in magnesium based alloys, which relates to the DARE research theme “Magnesium Alloys less dependent on Rare Earths”.

Dr. Enrique Galindo-Nava – Royal Academy of Engineering Fellow

My work aims to optimise material properties, whilst ensuring their appropriate manufacturability using modelling and experimentation. I am interested in studying advanced alloys such as Ni- & Ni-Co-based superalloys, steels, titanium and magnesium alloys and I have worked across the research themes within DARE.

Dr. Alexander (Sandy) Knowles – EPSRC Doctoral Prize & EURO-Fusion Research Fellow

MEng Materials Science, University of Oxford (2007-2011)

PhD Materials Science & Metallurgy, University of Cambridge (2011-2015)

DARE PDRA (2015-16)

DARE Associate Researcher (2016-present)

My research with the DARE programme relates to the development of new titanium alloys. One direction has focused on the design, characterisation and testing of new high strength beta titanium-molybdenum alloys reinforced with intermetallic precipitates with a bcc superlattice structure.

A second direction supports the development of new commercial titanium alloys in collaboration with TIMET. On TIMETAL 575, the mechanisms of Si strengthening additions are being studied using advanced electron microscopy and mechanical testing. While detailed fatigue studies are being performed at multiple lengthscales on TIMETAL 407, so as to further understand its impressive fatigue performance.
