Mechanical tests of irradiated materials rely on small sample volumes due to i) limited space in test reactors and ii) limited damage depth for accelerator irradiations. Understanding the connection between the micro- and nano- scale to bulk testing techniques is therefore valuable. As part of an effort to extract useful mechanical response from limited volumes of irradiated materials, multiple mechanical testing techniques were performed on neutron irradiated FeCrAl alloys. Techniques spanning bulk miniature tensile, shear punch, micro-hardness, nano-indentation, and micro-pillar compression tests were conducted. Merits of the techniques and relationships comparing the bulk tensile properties to the micro- and nano-scale testing will be discussed.
