Microstructure and Mechanical Properties of Steels

Mechanical properties of the austenitic steel 316L (both solution annealed and cold worked) and the low activation martensitic steel Optifer have been investigated by small punch tests. The samples, in the form of TEM disks, were irradiated in the target of the spallation source SINQ to displacement doses of up to 11 dpa. Values for yield strength, ductility and fracture energy as evaluated from punch tests are given.
