Dissolution of copper precipitates in an Fe-1.3wt%Cu alloy under Fe+ ion irradiation
The stability of Cu precipitates in an Fe-1.3wt%Cu alloy under 300 keV Fe+ ion irradiation has been investigated using transmission electron microscopy and high-resolution electron microscopy.

| Summary: | The stability of Cu precipitates in an Fe-1.3wt%Cu alloy under 300 keV Fe+ ion irradiation has been investigated using transmission electron microscopy and high-resolution electron microscopy. The irradiations were carried out between room temperature and 550 degrees C at displacement rates of 10(-3) to 10(-2) dpa(s)(-1) to fluences of up to 30 dpa. Copper precipitates were found to keep their shape but decrease in size under all irradiation conditions. The results are discussed within the framework of a competitive process between irradiation induced ballistic destruction of precipitates by cascades and irradiation-enhanced precipitation. |
