Fig. 3.2.10. Apparatus for Studying the Extent
of Alloying Between Beryllium and Various Metals
le Immersed in Molte
plate on lnconel does not elimi-
nate alloying reactions with beryllium when the
two materials are in contact while immersed in
high-temperature sodium, but the plate does sub-
stantially reduce the extent of alloy formation.
Approximately 4 mils of lnconel was consumed
the formation of the 24-mil nickel-beryllium
alloy layer which was found where the lnconel
and the beryllium were in direct contact (Fig.
3.2.13~). The major portion of reaction layer
was found to be Be,Ni, with a smoll percentage
of BeNi adjacent to the Inconel. The reduction
in alloy formation brought about by the 2-mil chro-
mium plate is illustrated in Fig. 3.2.13b. A second
test is now under way in which the effectiveness
of 4- and &mil chromium platings will be evaluated.
