Sarah George BSc Phd (Cape Town)

Dr Sarah George completed both her Masters and Doctoral qualifications at the Centre for Materials Engineering. Her research areas include the influence of solidification on structure and performance of materials, notably Aluminium. Her interest in thermo-mechanical processing has been supported by her skill in Gleeble operation , in particular the design of the experiments for illustrating these processes.
