Room temperature micro-tensile tests were successfully performed on F82H specimens neutron-irradiated at 573 K up to 5 dpa and unirradiated using a focused ion beam (FIB) device. Dimensions of the gauge section for micro-tensile specimens were about 10 µm (length) × 1 µm2 (area). These specimens were fabricated in a FIB device. The tensile properties obtained on specimens of micrometer size qualitatively agreed with results from millimeter size specimens. Using this micro-tensile testing technique is considered to become very useful data in combining the micro-tensile data on ion irradiated F82H with data on neutron irradiated material. This method overcomes the limitation on obtaining mechanical property on ion irradiated specimens to only micro-indentation testing.
