摘要: Abstract The temperature and time dependence of high stress relaxation in polycrystalline Magnox AL80 is analysed. Results are described by an exponential law for creep. parameters this may be interpreted according to a model thermally activated glide which vacancy-producing jogs the principal obstacles dislocation movement.
