GAS-METAL REACTIONS WITH IRON- AND NICKEL-BASE
HEAT RESISTANT ALLOYS
An Interpretive Literature Survey
INTRODUCTION
In recent years much work has been done in development of alloys
that withstand the effects of high temperature. Such alloys must retain
mechanical integrity at high temperature, and must also remain relatively
inert toward the oxidizing environments of service conditions.
The gas-turbine engine required alloys which would perform at
temperatures higher than the maximum service temperature of ordinary
carbon steel in air. Additions of chromium resulted in higher resistance
to scaling by oxidation; aluminum was even more beneficial. ( 1)
Demands for higher thermal efficiency in the gas turbine and jet
engine led to development of the nickel- and cobalt-base superalloys.
Proper alloying additions to nickel have produced alloys which retain good
creep and stress-to-rupture characteristics and, in addition, excellent
corrosion resistance at high temperature.
This report reviews the literature concerning the compatibility of
stainless steels and nickel-base alloys with various gases which might be
present in or around a high temperature nuclear reactor. Cobalt-base
alloys are excluded because of their unfavorable activation characteristics
under neutron bombardment. Many of the investigations on this subject
are not generally applicable because they have evaluated heat-resistant alloys
for a particular function. Those investigations of particular pertinence
are reviewed. Most of the major progress in the field has been covered,
but no effort has been made to present a complete bibliography. Some
fundamental information on alloy oxidation is included, which hopefully
will suggest further avenues of research.-2-
