✦ Synopsis

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 × 10^7^ 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.

The paper describes how the K,< fracture toughness of a high-purity Fe-2O%Co-lS%Cr-S%Mo maraging alloy is influenced by other mechanical properties and metallurgical factors. Particular consideration is given to the influence of residual oxygen content and to the strain-hardening characteristics of
