Available in PDF, EPUB and Kindle. Book excerpt: An experimental rig has been constructed for testing the fretting fatigue behavior of two materials in use in gas turbines, viz. Ti-6Al-4V and Inconel 718. Initial tests on Ti-6Al-4V show that the fatigue life is reduced as the temperature is raised and this is associated with the development of a layer structure on the surface. (Author).

This book was released on 2002-03-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research is to investigate the fretting fatigue behavior of the titanium alloy Ti-6Al-4V at elevated temperature is investigated. Fretting and plain fatigue experiments are conducted at 260 . Crack initiation location and crack initiation orientation is measured and fretting and plain fatigue life data of the specimens from these tests are obtained. Fatigue parameters capable of predicting the number of cycles to specimen failure, the crack location and the crack orientation along the contact surface are analyzed. The parameters are calculated by using the computed stresses and strains obtained from the finite element analysis. The mechanisms responsible for the fretting fatigue crack initiation are determined. The effect of elevated temperature is examined by comparing room and elevated temperature fretting and plain fatigue data.

Available in PDF, EPUB and Kindle. Book excerpt: Shot-peened titanium alloy Ti-6Al-4V and nickel-based super alloy IN100 were subjected to plain and fretting fatigue under cylinder-on-flat contact condition at room temperature. Measurement of compressive residual surface stress from shot-peening before and after fretting showed relaxation, which was significant in IN100 and near the contact surface. The fretting fatigue life of IN100 did not improve significantly due to shot-peening, while there was considerable improvement for Ti-6Al-4V and relatively less relaxation of the residual surface stress. Further, fretting had a relatively more detrimental effect on the fatigue performance of Ti-6Al-4V than in the case of IN100. A critical plane-based fatigue crack initiation model, a modified shear stress range parameter, was computed from finite element analysis for two levels of residual surface stress relaxation: no relaxation and complete relaxation. This analysis suggested that not only crack initiation but also propagation should be considered to characterize fretting fatigue behavior of shot-peened specimens; however, it showed an appropriate trend with the measured fretting fatigue life and agreement with several other experimental observations.

This book was released on 2000 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where fretting fatigue of titanium alloy gas turbine engine component is concerned, the effect of temperature on fretting processes can be quite significant. Service exposed third stage compressor blades, operating at 454°C or 850°F, showed severe signs of fretting, wear, CuNiln coating delamination, oxidation and pitting on the dovetail pressure surfaces. Under cyclic loading conditions fretting fatigue cracks, initiated in these damaged areas, can cause dramatic reduction in fatigue life of these components leading to potential catastrophic failure. A study has been carried out to evaluate the influence of various surface treatments, such as ion treatments, coatings and shot peening, on the fretting fatigue life of titanium alloy gas turbine engine components at elevated temperature. Results from high temperature fretting fatigue and pin-on-disk wear tests are discussed in this paper. Significant contrast between the wear and fatigue test results illustrates the potential dangers of using sliding wear tests to rank surface treatments for fretting fatigue amelioration.

Download or read book Engineering Tribology written by G.W. Stachowiak and published by Butterworth-Heinemann. This book was released on 1993-06-30 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interdisciplinary nature of tribology encompasses knowledge drawn from disciplines such as mechanical engineering, materials science, chemistry and physics. The interaction between these different fields of knowledge to achieve the final result, the control of friction and wear, is reviewed in this volume. This interdisciplinary approach has proven to be a very successful way of analysing friction and wear problems. In many cases tribology is viewed as an inaccessible subject which does not produce useful answers. In this volume the authors redress this problem by providing a comprehensive treatment of the subject. A basic feature of the book is the emphasis on describing various concepts in an accessible manner for the benefit of non-specialists. This principle is applied from the beginning of the book, where the reader is introduced to the fundamental concept of tribology. This concept is then often used to show how the various topics in tribology are interrelated to form one coherent subject. A direct graphical illustration of the mechanisms controlling tribological phenomena is presented. Carefully prepared diagrams allow rapid appreciation of the basic ideas and facts in tribology. The numerical analysis of hydrodynamic lubrication is supported by a number of computer programs which are included in the book. The control of wear is given extensive treatment with a thorough discussion of lubricant additives, solid lubricants and surface coatings. The effectiveness of coatings in suppressing specific forms of wear is analyzed together with the methods of coatings deposition. The book contains 474 figures and 44 tables. More than 1000 references are provided to give the reader access to more specialized information if required. The volume is intended to provide graduates in engineering or materials science with an understanding of the fundamental concepts of friction, wear and lubrication.

Download or read book Effect of Contact Pressure on Fretting Fatigue of High Strength Steel and Titanium Alloy written by N. Maruyama and published by . This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of contact pressure on fretting fatigue behavior has been studied using a high strength steel and a Ti-6Al-4V alloy. In steel, at higher stress amplitude, the fretting fatigue life decreased monotonously with increasing contact pressure. At lower stress amplitude, it exhibited a minimum at a low contact pressure and a maximum at an intermediate contact pressure, then decreased again and became constant at high contact pressures. The fretting fatigue strength at 107 cycles was high at an intermediate contact pressure. In titanium alloy, the fretting fatigue life showed a similar contact pressure dependence. The frictional force increased monotonously with increasing contact pressure. The initiation site of the main crack depended on the contact pressure and had a close relation to the width of stick region at the fretted area. The contact pressure dependence was discussed in terms of stress concentration at the fretted area.

This book was released on 2004-03-01 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fretting fatigue behavior of Ti-6A1-4V was investigated in laboratory air and under a controlled environment consisting of synthetic seawater. Fretting fatigue tests were performed for both low and high cycle fatigue regimes. Finite element analysis was utilized to model and analyze the experimental data. The applied stress range and the Modified Shear Stress Range were evaluated as potential fatigue parameters. The results found from this study can be summarized as: (1) seawater had a deleterious effect on fretting fatigue life in the low cycle fatigue regime but improved life in the high cycle fatigue regime, (2) although the Q/P ratio for both conditions increased with an increasing applied stress, the difference between the two conditions was negligible, (3) debris from dry samples contained titanium and oxides while the debris from seawater samples contained titanium, oxides, and seawater contaminants, (4) fretting scar volume was larger under seawater conditions than dry conditions, (5) there were more, closely spaced striations on the fracture surface of the dry samples than of the seawater samples, and (6) both the applied (far field) stress range and the Modified Shear Stress Range can potentially be used as conservative fretting fatigue parameters under high cycle fatigue conditions.
