Swinburne's School of Engineering present a seminar by Dr Bo Chen, Coventry University (UK).

Title of research presentation

In-situ Neutron Diffraction and Multi-scale Material Characterisation Techniques for Studying High Temperature Materials Performance and Structural Integrity.

Abstract

Modern technological progress, for example for electrical power generation, demands the use of engineering materials at increasingly higher temperatures. As a consequence of high temperature exposure, there are changes in material internal state. As an example, Type 316H austenitic stainless steel is widely used in nuclear power generation plant such as the UK’s Advanced Gas Cooled reactors (AGRs). Progressive changes in the underlying microstructure of Type 316H stainless steel are observed over the high temperature service life (>30 years). Thus, there is a need to develop improved understanding and predictive models of the evolution of the key microstructural features that describe mechanisms in controlling materials performance.

In this talk, I will present some key research outcomes in support of lifetime extension of the UK’s AGR reactors. A particular emphasis will be given to the importance of developing mechanistic understandings of material performance, via employing complementary multi-scale research methodology, which helps to bridge the gap between the nanometre length-scale microstructures and the millimetre to centimetre length-scale mechanical test specimens.
