Deformation of materials is typically modelled on their performance during uni-axial tests. However, many modern metal-forming processes subject alloys to very complex loading conditions. Limited understanding of plastic deformation under multi-axial loading constrains the attainable geometry of the manufactured components. Bi-axial testing provides valuable insight about the intricate deformation mechanics. The miniature bi-axial load frame constructed by the student will be used to investigate microstructure-level deformation of selected high-performance alloys. Over the course of the project the student will develop in-house capability for bi-axial tensile testing of advanced alloys inside a scanning electron microscope. The student will use digital image correlation and crystal orientation mapping (electron back-scatter diffraction, EBSD) to measure how deformation is localised within the different microstructural features of the alloys.
International students applying must be able to provide evidence and pay the difference between the UK Home Fee and International Fee.
