Book excerpt: The complex geometry of cylinder heads in heavy-duty diesel engines makes grey iron or compact graphite iron a preferred material choice due to its price, castability, thermal conductivity and damping capacity. Today’s strict emission laws have increased the demands on engine performance and engine efficiency. This means that material properties such as fatigue resistance need to be improved. Shot peening is often used to improve the fatigue resistance of components and the benefits of shot peening are associated with the induced compressive surface stresses and surface hardening. How different shot peening parameters can affect fatigue strength of grey and compact graphite iron has been investigated within the project underlying this thesis. To do this, X-ray diffraction (XRD) was utilized for residual stress measurements, scanning electron microscopy (SEM) for microstructural characterizations and mechanical fatigue testing for mechanical quantifications. The ultimate aim of this work has been to increase the fatigue resistance of cast iron by residual stress optimization. XRD measurements and SEM examinations revealed that the shot peening parameters shot size and peening intensity significantly influence residual stresses and surface deformation. Residual stress profiles, similar to the one general considered to improve the fatigue strength in steels, were obtained for both grey and compact graphite iron. Uniaxial push-pull fatigue testing on grey iron with these shot peening parameters reduced the fatigue strength with 15–20 %. The negative effect is likely related to surface damage associated with over peening and relatively high subsurface tensile residual stresses. With very gentle shot peening parameters, the uniaxial fatigue strength were unaltered from the base material but when subjected to bending fatigue an increase in fatigue strength were observed. An alternative way to increase the fatigue strength was to conduct a 30 min annealing heat treatment at 285 XC which increased the fatigue strength by almost 10 % in uniaxial loading. The improvement could be an effect of favourable precipitates forming during the annealing, which could hinder dislocation movement during fatigue. Measuring residual stresses using XRD and the sin2 -method demands accurate X-ray elastic constants (XEC) for meticulous stress analysis. The XEC referred to as 1~2s2 should therefore always be calibrated for the specific material used. The experiments conducted revealed that the XEC value is independent of the testing method used in this work. A small correction from the theoretical value should be applied when the material contains small amounts of residual stresses. The amount of residual stresses has a great impact on the XEC and thus on the stress analysis. Concluding that proper analysis of residual stresses in cast iron is not straight forward.
Book Synopsis Handbook of Residual Stress and Deformation of Steel by : George E. Totten
Download or read book Handbook of Residual Stress and Deformation of Steel written by George E. Totten and published by ASM International. This book was released on 2002 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Examines the factors that contribute to overall steel deformation problems. The 27 articles address the effect of materials and processing, the measurement and prediction of residual stress and distortion, and residual stress formation in the shaping of materials, during hardening processes, and during manufacturing processes. Some of the topics are the stability and relaxation behavior of macro and micro residual stresses, stress determination in coatings, the effects of process equipment design, the application of metallo- thermo-mechanic to quenching, inducing compressive stresses through controlled shot peening, and the origin and assessment of residual stresses during welding and brazing.

Book Synopsis Fatigue of Metals by : P. G. Forrest
Download or read book Fatigue of Metals written by P. G. Forrest and published by Elsevier. This book was released on 2013-10-22 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of Metals provides a general account of the failure of metals due to fatigue, a subject of great practical importance in the field of engineering and metallurgy. The book covers a wide range of topics on the study of the fatigue of metals. The text presents in the first three chapters the characteristics and detection of fatigue fractures; methods of fatigue testing; and the fatigue strengths of different materials. The resistance of materials to fatigue under complex stress; the determination and effects of stress concentration; influence of surface treatment on fatigue strength; and effects of corrosion and temperature are also studied in detail. In relation to the previous chapters of fatigue information, a chapter is devoted to engineering design to prevent fatigue. The last two chapters provide a brief historical survey of the developments of the study of the mechanism of fatigue and fatigue of non-metallic materials such as wood, plastic, rubber, glass, and concrete. Mechanical engineers, designers, metallurgists, researchers, and students will find the book as a good reference material.
