摘要: Compressive creep tests have been performed on polycrystalline hyperstoichiometric uranium dioxide, as a function of temperature, stress and deviation from stoichiometry. Under low stresses measured steady-state rates for UO2+x increase linearly with applied stress, σ, oxygen excess, x. Creep tested at high follow power-law dependence the form e ∝ σn where 4
