Irradiation creep model for materials for fusion energy

What is it about?

Structural materials deform when mechanical force (stress) is applied in sufficient magnitude. If the stress is not high enough, no deformation takes place. However, at high temperatures, deformation can take place even at stresses below the mechanical limit. This mode of deformation is known as 'creep'. Under irradiation, such as in future fusion energy devices, creep can occur even at low temperatures, however, which makes it a critical issue for materials performance. We have developed models that help us understand irradiation creep iand hopefully aid in the design of better fusion energy structural materials.
