Abstract The corrosion behavior of RAFM JLF-1 (Fe–9Cr–2W) steel in static N-added Li (0.5 wt.%N) at 600C for times up to 750 h was investigated. The kinetics of weight change and peculiarities of corrosion interac-tion were determined. Samples showed intensive weight losses during first 120 h while with an exposure time the weight losses became slower. Corrosion attack proceeded most intensively along the boundaries of prior austenitic grains, martensite packets and laths, causing formation of the extremely relief surface. The porous and softened ferrite zone depleted markedly in Cr was formed beneath the relief surface. The martensite to ferrite transformation occurred in this zone. The weight losses of steel in N-added Li were about 25 times higher than those in ‘‘pure’’ Li (0.004 wt.%N) under the same time–temperature condi-tions of tests. The scheme of corrosion interaction in ‘‘JLF-1 steel–Li[N]’’ system was proposed.
