Problems of Fatigue of Metals in a Vacuum Environment

Abstract

The current state of knowledge of the effects of a vacuum environment upon fatigue is summarized in this report. The effects of temperature, pressure variations, prolonged exposure, and environment composition on fatigue life are discussed in detail. In addition, studies of the surfaces of specimens fatigued in vacuum are described. Results indicate that fatigue life is better in vacuum than in air for most of the materials investigated. Most investigators attribute this increase in life to decreased oxidation of the material in the vacuum environment.
