THE CORROSION INFLUENCE OF PB-LI ON MICROSTRUCTURE AND MECHANICAL PROPERTIES
Abstract
In this work, corrosion experiments on 9Cr-ODS andCLAM steels were carried out in static Pb-Li at 873 K for250 h. Both steels showed weight loss and softening nearthe surface after the exposure. Tensile properties did notchange and creep properties degraded slightly for 9Cr-ODS steel. In contrast, CLAM steel showed hardening byincrease in tensile strength and creep rupture time, anddecrease in minimum creep rate and reduction of area.The metallurgical analyses showed that the both steelswere non-uniformly corroded by preferential corrosion atgrain and sub-grain boundaries. Near the surface,carbides were lost and Cr was depleted to several tens ofPm depth. The depletion was heavier for 9Cr-ODS thanfor CLAM. The corrosion mechanism was proposed to bea loss of protective oxide layer followed by dissolution ofCr in matrix into liquid Pb-Li. The more pronouncedcorrosion effect on 9Cr-ODS than on CLAM may be dueto finer grain and sub-grain size enhancing preferentialattack by Pb-Li at the boundaries, or lack of Mn in 9Cr-ODS, which can form protective layers for CLAM.
