Type 1020 mild steel, IF-steel[reg sign](registered trademark of Armco Steel Corporation, Middletown, Ohio), and TI-Namel were exposed in molten lithium hydride (LiH) at 800C for cumulative times approaching 300 h. Mild steel decarburized at an extreme rate with the affected area exhibiting tremendous grain growth. In contrast, IF-steels[reg sign] and TI-Namel do not experience decarburization or grain growth during identical exposures to LiH. All three steels experience net weight gains during extended exposure, and the data suggest that lithium penetration into the steel is the primary source of weight gain.
