| Research Abstract |
In order to study the factors which determine the incubation period of void swelling in austenitic stainless steels, Ni, model alloys such as Fe-Cr-N and commercial steels were irradiated with electrons and neutrons. Damaged structures were investigated by positron annihilation lifetime measurement, transmission electron microscopy and electrical resistivity measurement. In alloys of no formation of metal carbides, the mobility change of point defects by alloying elements affects the period. In metal carbide forming alloys, the carbides play an important role for the determination of the period.
