| Abstract Scope |
Ion irradiation is an attractive alternative to neutron irradiation for studying the effects of radiation damage on materials as it imparts relatively high doses (several dpa) in a short time frame (days) without activating the samples. However, the thin layer of material radiated by this technique requires the employment of small-scale testing methods such as micro-mechanical testing.
Micro-mechanical testing is more suitable for the assessment of mechanical properties when the grain size is small compared with the sample size. Here, an overview of a series of studies on the effects of ion irradiation on the mechanical properties of three different materials with small grains (<2 μ m) is presented. These studies on an oxide dispersion strengthened (ODS) steel MA957, pure Ni and Ni-SiC dispersion strengthened alloy employ in situ micro-tensile testing inside the scanning electron microscope. The results are discussed in terms of their relevance to bulk mechanical properties. |
