    Abstract : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. READ MORE

  5. 3. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films

    Author : Per Fredriksson; Peter Gudmundson; Christian Niordson; KTH; []
