Book The Influence of Surface Phenomena on the Mechanical Properties of Structural Materials   fatigue of Aluminum in Vacuum

Download or read book The Influence of Surface Phenomena on the Mechanical Properties of Structural Materials fatigue of Aluminum in Vacuum written by John L. Ham and published by . This book was released on 1963 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques were developed for evaluating the fatigue life of metals by reverse bending in con trolled gaseous environments including high vacuum, and bombardment. These techniques were applied to electropolished specimens of commercia lly pure, half hard rolled aluminum sheet. The fatigue life of aluminum in reverse bending at 125 to 140 cycles per second was found to be about seven times longer in vacuum than in wet air and about four times longer in vacuum than in dry air. The cyclic strain causes more surface roughening in vacuum than in air. A hypothesis based on adsorption equilibrium and immunization to cracking by work hardening is proposed to explain the step change in life with pressure. The effectiveness of bombardment is ascribed to prevention of crack contamination by migration of mobile surface gas films. (Author).
