National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Materials compatibility testing for a pilot-scale oxide reduction system.

DE2001757525

Publication Date	2000
Personal Author	Totemeier, T. C.; Herrmann, S. D.
Page Count	16
Abstract	Materials compatibility tests were performed on five candidate steels for the pilot-scale oxide reduction system currently under development at Argonne National Laboratory-West. Three stainless steels (type 316L, 304, 347) and two alloy steels (2.25Cr-1Mo and 9Cr-1Mo-V) were evaluated. Small, Swagelok-sealed capsules constructed from each steel were loaded with a LiC1 salt solution and exposed at 725degC for 30, 60, and 90 days. The LiC1 salt solution contained 3.5 wt% Li2O, 1 wt% Li3N, and was saturated with Li metal. The extent of corrosion was assessed following exposure by destructive metallographic examination of each capsule. The extent of corrosion observed varied widely, from essentially none to full penetration of the capsule wall. The primary form of corrosion for all steels was grain boundary porosity and depletion of Cr from the exposed surface.
