| Abstract Scope |
Mechanical property evaluation of neutron irradiated materials is the technique of choice for understanding degradation in service. However, the limited number of facilities and long irradiation times severely restricts the testing throughput. Ion irradiation is one approach to screening candidates quickly as the irradiation times are orders of magnitude less, with the limited ion penetration depth as a major drawback to the technique. In light of this, we have developed novel techniques for extracting additional information from this region. Our studies have focused on improving existing nanoindentation approaches, developing microshear compression testing, and expanding mechanical testing to the mesoscale. These techniques span the ranges typically achieved by light and heavy ions, and have provided new insights into the effects of radiation damage on materials. |
