Nanostructured materials are of great interest to the radiation damage community. In this work we show recent atom probe tomography data on MA957 irradiated in FFTF to doses >100dpa at different temperatures. These data suggest changes of the microstructure of the ODS alloy. The concept of nanostructured alloys influences the development of new alloys offering a large amounts of interfaces for defect trapping. This is incorporated in the concept of fcc/bcc (Cu/Nb) nanostructured alloys which contain a large number of defect sinks as well. We present a novel concept of manufacturing these alloys via ball milling and subsequent high pressure torsion compacting at ambient temperatures realizing the idea of nanostructured alloys in this alloy system. Several samples of this new alloy were produced and characterized. It was found that the alloys show a remarkable temperature stability of the nm sized clusters to temperatures of 500°C.
