摘要: Single-crystal Cu micro-pillars were self-ion irradiated up to 190 displacements per atom, a level commensurate with damage expected after long exposure in reactor environment. Compression experiments performed along the ⟨ 110 ⟩ 10% strain compared against un-irradiated Cu. Two specimen configurations explored: large 10 μm tall and small 4 μm pillars. Compared Cu, pillars exhibited flow stress increase of more than 500 MPa able attain peak stresses approaching 1 GPa. These results are discussed context an end range effect, gradient size effects.
