Beschreibungen/Notizen

• In common with many other ceramics, uranium dioxide exhibits low creep ductility in both bending and compression loading modes. It is demonstrated that if the material and test conditions are suitably optimised, failure strains in compression of over 100% true strain are possible. The growth and reorientation of grain-boundary pores during such superplastic deformation are studied and a model to explain their behaviour is proposed.
