EFFECT OF LOW PRESSURES ON THE MECHANICAL BEHAVIR OF METALS.
Abstract
Results of a study on the creep, tensile, and fatigue behavior of metals at low environmental pressures are presented. Changes in the activation energy for creep of aluminum single crystals were measured as pressure was varied from 10 to the -4th power to 10 to the -7th power toor. Effects of vacuum on the tensile properties of single and polycrystalline aluminum are presented. Variations in the tensile properties of 316 stainless steel and 4043 aluminum with pressures in the range 760 to 10 to the -8th power torr are also presented. Variations in the fatigue life of 1100 aluminum as a function of pressure in the range 760 to 10 to the -6th power torr are given. (Author)
