Available in PDF, EPUB and Kindle. Book excerpt: A development program was conducted on M-50 and VascoJet MA to determine the improvements possible in bearing steels by the incorporation of a hotcold working (ausforming) treatment in their processing. Primary emphasis was on the improvements possible in rolling contact fatigue. In support of this, heat treat, corrosion, hardness and microstructural studies were performed. The ausforming process as applied to the rolling contact fatigue life of M-50 bearing steel will substantially improve life (exceeding 800%). This will be a significant factor in meeting the long life bearing requirements for advanced air breathing propulsion systems. A metallurgical analysis was conducted and a mechanism is proposed which is thought to be the primary factor in providing the significant improvements in rolling contact fatigue life. Evidence is presented which indicates that the life improvement is primarily due to more uniform carbide dispersion, reduction of massive carbide particles, and reduction in martensite platelet size. These microstructural changes are believed to be associated with strain induced precipitation and its interplay with strain hardening during the deformation cycle. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Army Materials and Mechanics Research Center has con ducted the Sagamore Army Materials Research Conference in coop eration with the Materials Science Group of the Department of Chemical Engineering and Materials Science of Syracuse University since 1954. The purpose of the conference has been to gather to gether scientists and engineers from academic institutions, in dustry and government who are uniquely qualified to explore in depth a subject of importance to the Army, the Department of Defense and the scientific community. This volume, Advances in Deformation Processing, addresses the areas of Analytical Advances, Workability, Processing to Optimize Properties, Advanced Applications - Materials, and Advanced Applications - Processes. The dedicated assistance of Mr. Joseph Bernier of the Army Materials and Mechanics Research Center throughout the stages of the conference planning and finally the publication of the Sagamore Conference Proceedings is deeply appreciated. The support of Helen Brown DeMascio of Syracuse University in p- paring the final manuscript is acknowledged. The continued active interest and support of these conferences by Dr. A. E. Gorum, Director of the Army Materials and Mechanics Research Center, is appreciated. Syracuse University Syracuse, New York The Editors vii Contents SESSION I INTRODUCTION A. E.

Book excerpt: Gearing technology in its modern form has a history of only 100 years. However, the earliest form of gearing can probably be traced back to fourth century B.C. Greece. This publication draws together current gear practice and integrates it with recent advances in the technology. The history of gearing is reviewed briefly in the 'Introduction.' Subsequent sections describe types of gearing and their geometry, processing, and manufacture. Both conventional and more recent methods of determining gear stress and deflections are considered. The subjects of life prediction and lubrication are additions to the literature, not having been treated before. New and more complete methods of power loss prediction as well as an optimum design of spur gear meshes are described. Conventional and new types of power transmission system are presented. (Author).
Download or read book Improvement of the Rolling Contact Fatigue Resistance in Bearing Steels by Adjusting the Composition of Oxide Inclusions written by Tomoko Sugimura and published by . This book was released on 2014 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements in the rolling contact fatigue resistance of bearing steels need to be made, and various researches to achieve this have been implemented. It is particularly important that, among the non-metallic inclusions, the quantity of large-size oxide inclusions be reduced. Therefore, studies looking at minimizing oxide inclusions have been carried out. More recently, however, a new approach to improving the rolling contact fatigue resistance, different from previous methods, has been undertaken. It has been reported that the condition of the contact at the interfaces between the matrix and non-metallic inclusions is important because it affects the stress state around the inclusions, and that this condition needs to be considered to improve the fatigue resistance of bearing steel. In this paper, to develop bearing steel with a rolling fatigue life better than is currently the case, the relationship between the rolling contact fatigue resistance and the composition of oxide inclusions is investigated. By controlling the composition of the oxide inclusions, fatigue failure was avoided in a thrust-type rolling contact fatigue test, and the fatigue life (L10) achieved was greater than 200 million revolutions. The reason for this improvement is considered to be the absence of voids at the interface between the matrix and the non-metallic inclusions, which would otherwise have a negative effect on the fatigue life.
