EFFECT OF FLUID ENVIRONMENT ON TORSIONAL FATIGUE FAILURE.

Abstract

A study of the interaction of the relevant parameters leading to fatigue failure under conditions of torsional loading was initiated. An experimental program aimed at studying the effects of strain amplitude, microstructure, lubricant chemistry and lubricant viscosity on the initiation of fatigue cracks and their subsequent growth to failure was developed. Experimental techniques were developed to monitor both the surface and internal damage accompanying the fatigue process as well as the changes in work hardening behavior during fatigue. The results of testing bearing grade 52100 steel in two fluid environments are presented. (Author)
