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. |
