Abstract This paper is a study of the fatigue properties of the alloy
columbium - one percent zirconium in reverse bending. This paper
also is a design study of a satisfactory plate reverse bending fatigue
specimen configuration for use with the General Electric PRB pneumatic
testing machine. Selected tensile tests were also run on
columbium one percent zirconium to provide reference strength data
with which to compare the results of the fatigue tests.
The fatigue tests showed the fatigue strength of columbium -
one percent zirconium to be higher than that of pure columbium. No
endurance limit was found for the alloy in the range of testing from
10⁵ to 10⁷ cycles of reverse bending. A successful reverse bending
fatigue specimen was designed with a triangular constant stress
region where failure occurred. Generous fillets prevented unacceptable
fatigue failure in the machine grips.
