Abstract
Fatigue tests have been conducted on commercially produced cast Co-Cr-Mo alloy in tension-tension while surrounded by a physiological solution at 37°C The data have been analyzed by statistical techniques to yield an allowable stress such that there is 95% confidence of less than one failure in 1,000 after 5 × 107 cycles of stress fluctuation. These results are valid for a substantially sounder material than may be common in commercial use and therefore a more conservative allowable stress probably ought to be used for design purposes.Keywords
