This book was released on 2002-04-29 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal fatigue is an essential consideration for engineers and researchers who are looking at factors that cause metals to fail through stress, corrosion, etc. This is an English translation of a book originally published in Japan in 1993, with an additional two chapters on the fatigue failure of steels and the effect of surface roughness on fatigue strength.

Available in PDF, EPUB and Kindle. Book excerpt: Press hardening of Boron steels, mainly the 22MnB5 grade, has been implemented during more than a decade in several structural components of the automotive sector, mostly in the body-in-white (BiW). The process combines sheet forming and heat treatment in one single die quenching step, to produce components with complex geometry and strength up to 1600 MPa. In press hardened steels, fatigue behaviour is very sensitive to surface defects or irregularities, either intrinsic or introduced during forming operations such as trimming. This work addresses the understanding and prediction of fatigue resistance of press hardened steels from a Linear Elastic Fracture Mechanics (LEFM) approach. The size of fatigue originating defects has been evaluated and used to estimate the fatigue limit for different surface conditions (coated and uncoated), different coatings (Al-Si and Zn) and different edge conditions (polished and mechanically trimmed).

Book excerpt: This paper represents the first part of a systematic investigation of factors affecting the fatigue resistance of surface-hardened steel components. The adopted approach is to view a surface-hardened member as a composite material consisting of a high strength, low ductility case and a lower strength, higher ductility core. A series of smooth axial specimens, representing case and core carbon contents, were prepared to determine cyclic stress-strain and strain-life curves. The cyclic properties obtained from these tests were then used to analyze and interpret the cyclic behavior of carburized specimens. Both axial and bend specimens were carburized and subjected to constant amplitude, strain-controlled fatigue tests. A discontinuity in the resulting strain-life curves, representing a shift from surface to subsurface crack initiation, is predictable from comparison of the strain-life curves for simulated case and core material. Finally, a relation is developed to determine optimum casexore ratios taking into account cyclic material properties, residual stresses, strain gradient, and applied stress or strain level.

Download or read book Carburizing written by Geoffrey Parrish and published by ASM International. This book was released on 1999-01-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Based on his training in metallurgy and experience in a large British gear manufacturing company, Parrish reviews the microstructural features of metal products that have been carbon case-hardened, and the influence of those features on the more important material properties. He is not concerned with the carbonizing process at all. He primarily addresses students of engineering and ferrous metallurgy, but also stress and design engineers who might want to understand more fully the specifications of the materials they are considering for their designs. He wrote the eight articles to summarize the field's literature of the early 1970s for his own convenience, but at invitation, published them as a series in the Heat Treatment of Metals during 1967-77, and collected them for a first edition of the volume in 1980.

This book was released on 2013-01-25 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weld toe is a primary source of fatigue cracking because of the severity of the stress concentration it produces. Weld toe improvement can increase the fatigue strength of new structures significantly. It can also be used to repair or upgrade existing structures. However, in practice there have been wide variations in the actual improvements in fatigue strength achieved. Based on an extensive testing programme organised by the IIW, this report reviews the main methods for weld toe improvement to increase fatigue strength: burr grinding, TIG dressing and hammer and needle peening. The report provides specifications for the practical use of each method, including equipment, weld preparation and operation. It also offers guidance on inspection, quality control and training as well as assessments of fatigue strength and thickness effects possible with each technique. IIW recommendations on methods for improving the fatigue strength of welded joints will allow a more consistent use of these methods and more predictable increases in fatigue strength.

Download or read book Flame Hardening written by Hans Wilhelm Grönegress and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.
