Neutron-induced swelling of Fe-Cr-Mn ternary alloys. [LMFBR]

;

It appears that the swelling of Fe-Cr-Mn alloys is remarkably insensitive to both irradiation temperature (420 to 600/sup 0/C) and composition. The slight dependence of macroscopic swelling on manganese content is thought to be primarily the consequence of a composition-dependent densification, possibly associated with radiation-induced spinodal decomposition in the Fe-Cr-Mn Invar regime. The steady-state swelling rate of these alloys appears to be approx. 1%/dpa.
