| Abstract: | Specimen of Al-1% Cu aged to contain θ′ and stainless steels of various Ni and Cr contents have been irradiated in an HVEM. It has been found that the nature of the dislocation damage in the stainless steels is a complex function of composition and temperature; very irregular faulted loops, regular faulted loops and regular unfaulted loops are formed in varying proportions. In the Al-1% Cu, aged for varying times at 190 °C to produce θ′, the ageing times influences the amount of radiation damage in a complex manner. Virtually all the visible damage in these alloys is found either at the precipitate interface or at the electron entrance surface. |
