Notes:
A change of the mechanical property and microstructure of an Fe ion irradiatedpolycrystalline Fe-9wt%Cr model alloy to 1 dpa was examined using a nano-indentation andtransmission electron microscopy. We anticipated that irradiated damage would be formed up toabout 2.5μm and a displacement damage peak would be located at around 1.7μm from a surfacethrough a TRIM code calculation. A thick dark band was formed at about 1.5μm from a surfacewith an actual TEM observation, which is consistent with a displacement damage peak in the TRIMcode calculation. TEM observations showed that small defects with a Burgers vector a0〈100〉 and1/2a0〈110〉 are formed in irradiated Fe-9wt%Cr alloy. In the nano indentation test, the hardnessincrease due to irradiation induced defects was up to 0.6GPa which can be converted to a yieldstress increase of 200MPa
