RADIATION-INDUCED SEGREGATION IN HYDROGEN-IMPLANTED Fe-1wt%Ni ALLOY
注氢Fe-1wt%Ni合金中的辐照诱导偏析

Radiation-induced segregation of Ni element in Fe-1 wt%Ni alloy was investigated by ion accelerator and high voltage electron microscope. The results show that the complexes of Ni, vacancy and hydrogen diffuse towards voids due to the inverse Kirkendall effect. Ni atoms would precipitate along {110} planes near voids. Streak diffraction pattern from the coherent precipitates of Ni can be observed.
