Dr Biao Cai joined the University of Birmingham in October 2017 as a Lecturer of Metallurgy and Materials.

His role is to co-ordinate the University’s activities with Diamond Light Source (UK’s synchrotron X-ray) to facilitate the Diamond Birmingham Collaboration.

His current research focuses on developing and utilising in situ synchrotron, and neutron methods, to gain new understanding in micro-mechanics and physical metallurgy - feeding back into the development of new materials and manufacturing techniques.

Qualifications

PhD in Materials, University of Manchester.

Biography

Biao obtained a BSc and MSc in Materials from Central South University in China in 2009 and 2011, respectively. He went on to study for a PhD in Materials at the University of Manchester, and was awarded the degree in 2015. After that, he worked for two years as a post-doc at the University of Manchester on various projects ranging from alloy solidification to magma flow mainly, using state-of-the-art high speed synchrotron X-ray tomography. He was based at the Research Complex at Harwell, Rutherford Appleton Laboratory, Harwell Campus, Oxfordshire during his PhD and post-doc.

He became a Lecturer in the School of Metallurgy and Materials at the University of Birmingham in October 2017. His main role is to co-ordinate the Diamond-Birmingham Collaboration, which is a long-term collaboration established between the University of Birmingham and Diamond Light Source (UK’s synchrotron X-ray source).

Research

At the University of Birmingham, Biao’s main interest is in utilising synchrotron, and neutron based characterisation methods (tomographic imaging and diffraction), combining ‘traditional’ mechanistic and metallurgic approaches, to accelerate materials development, which includes:

-  4D imaging (high speed X-ray tomography) of the liquid flow and solidification processes influenced by magneto-hydrodynamic, gaining improved understanding of solidification under forced convection, which leads us to develop new methods utilizing magnetic fields to liquid metal processing

-  In situ mapping of microstructural evolution of deforming metallic alloys using X-ray/neutron diffraction and tomography, gaining improved understanding of micro-mechanics, leading us to design new alloys for extreme environments
