mole %) and in argon. Themsufts obtained to
date are summarized in Table 3.5.1.
The positions of the fractures in the specimens
tested at 1500OF in the fuel mixture are shown in
Fig. 3.5.18. Specimen No. 2 was tested at 3000

psi and No. 3 at 4000 psi. As may be seen, the
weld did not deform appreciably, compared with
the base metal, in the gage length. Metallographic
examination of the specimen tested at 1300OF
disclosed that the weld metal was more corrosion
resistant than the base metal.
