Available in PDF, EPUB and Kindle. Book excerpt: The microstructure-mechanical properties relationships, fracture toughness, fatigue crack growth and fracture surface morphology of J6 bainitic, manganese, and pearlitic rail steels were studied. Microstructure-mechanical properties correlation of the three rail steels under consideration revealed that the bainitic rail steel has the highest mechanical properties as compared with austenitic manganese steel (AMS) and pearlitic rail steels. AMS shows very few signs of being work hardened or toughened, which usually increases the mechanical properties of the material. In pearlite, the microstructure has more detailed features that contribute to its mechanical properties. The bainitic steel has more alloying elements that when mixed, create so many dislocations that the dislocations cannot move against each other. This is where bainitic steel derives its strength. Fracture toughness analysis (KIc) of the three rail steels, namely bainitic, manganese and pearlitic was performed. A valid KIc was determined for the pearlitic and bainitic steels based on the American Society of Testing and Materials (ASTM) E399 criteria.

Book excerpt: This volume presents a collection of papers on the theme of rail integrity, which were presented at a meeting in Delft from 24--26th June, 1992. Rolling contact fatigue is a failure mode which is increasingly being recognised as a threat to the reliability of modern heavy freight and high speed railway systems. These papers describe the current understanding of the problem and what rail steel technology and maintenance procedures have to offer to combat it.

Book excerpt: Baseline fatigue crack growth data at R = 0 and mechanical property data have been generated on 66 different rail materials which are in service on U.S. railroads. These data are evaluated, along with metallurgical variables such as chemical composition and microstructure, in an attempt to develop a correlation of mechanical and metallurgical factors affecting crack behavior in rail steels. The ultimate objective of this effort is the development of a rail failure model to enable the determination of safe inspection intervals, through prediction of fatigue crack growth in rail under service loading.

This book was released on 2014 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the integrity assessment and damage-tolerant design of components operating at elevated temperatures under cyclic loading conditions, evaluation of fatigue crack growth (FCG) properties in the threshold and Paris regimes is important. The FCG behaviors of a modified 9Cr-1Mo steel (P91) and SS 316L(N) for applications in the prototype fast breeder reactor to be commissioned shortly at Kalpakkam, India have been studied extensively in our laboratory over a wide range of temperatures. Some aspects of high-temperature FCG observed in these investigations will be reviewed in this paper. It has been observed that for many engineering alloys, dynamic strain aging plays an important role in the temperature-dependent variations in deformation and fracture behavior, including the FCG parameters. Another important aspect in deciding the FCG behavior is the crack closure behavior, the mechanisms of which may vary with temperature. Effect of crack closure and DSA on the FCG properties of P91 steel and SS 316L(N) welds will be discussed. The DSA mechanism has been identified from the activation energy for the process determined from the temperature dependence of the crack tip strain rates. During FCG of engineering materials, there can be stress shielding at the crack tip because of various factors, like crack bridging, branching, closure, etc. Effect of stress shielding at the crack tip at different conditions was quantified using a procedure incorporating the inter relations between compliance, crack length, and stress intensity factor. The paper will summarize the results of the above studies.

Available in PDF, EPUB and Kindle. Book excerpt: The Ad Hoc Committee on Rail Research, which is composed of representatives from the American Railway Engineering Association (AREA), the Association of American Railroads (AAR), and the American Iron and Steel Institute (AISI) Committee on Railroad Materials, formulated a program to investigate the effects of metallurgical properties, mechanical properties, and applied stress conditions on the service fracture behavior of carbon-steel rails. This paper presents the fatigue and fracture behavior of five rails having extremes in room-temperature tensile properties and Charpy V-notch toughness, and an analysis of the effect of this behavior on the in-service useful life of carbon-steel rails. These five rails were removed from service after 15 to 18 years of operation and were selected from a population of about 90 rails that were removed from service because they contained service-developed defects. A companion paper in this symposium describes the results of chemical analysis, hardness and tension tests, and the results of wear, deformation, metallographic, and fractographic analysis.

Available in PDF, EPUB and Kindle. Book excerpt: In a previous report, a fatigue crack propagation model was analyzed by considering fatigue crack propagation as a sequence of fatigue crack initiation events. This permitted correlation to be made between the fatigue crack growth resistance and low cycle fatigue properties of metals. Four steels were tested for low cycle fatigue behavior at the University of Illinois. Good correlation was obtained between the theoretically predicted crack propagation rate based on the measured low cycle fatigue properties of the four metals and experimentally observed crack propagation rates that were reported in the literature. Further, good estimates of crack propagation rates can be obtained on the basis of static tensile properties of the metals alone where cyclic properties are not available. (Author).

Book excerpt: Fatigue crack growth has been examined in pearlitic rail steels to determine the effect of grain boundary ferrite and nonmetallic inclusions on the rates of crack propagation under Mode I loading at ambient temperature. The influence of alternating and maximum stress intensity on fatigue crack propagation in these materials has also been evaluated. The data were obtained using single-edge notch specimens machined from the head of rails and the web of wheels. Cyclic loading was performed on a hydraulic test machine at various R ratios.

Book excerpt: Advancements in Powder Metallurgy: Processing, Applications, and Properties addresses a critical issue in academic scholarship by providing a comprehensive resource that has been lacking in the field. Existing books often fall short by merely covering the basics of powder preparation, sintering methods, and general applications, leaving scholars with a limited understanding of the subject. This knowledge gap has hindered innovative research and slowed the progress of metallurgy and mechanical engineering. However, with this groundbreaking book, the tide is turning. The book brings together twenty-one chapters authored by renowned pioneers in the field, delving deep into the realm of mechanical alloying. It covers the evolution of this technique, various alloy preparation methods, their advantages and limitations, and the synthesis of nanostructured materials. Unlike other resources, this volume goes beyond the basics and comprehensively covers the fabrication of a wide range of alloys, including biomaterials, hybrid nanomaterials, smart materials, super alloys, and ceramic materials, all achieved through the transformative process of mechanical alloying. By consolidating essential information in one resource, Advancements in Powder Metallurgy: Processing, Applications, and Properties fills a significant gap in the existing literature. It equips academic scholars and engineering students with the necessary knowledge to unlock the full potential of mechanical alloying and make meaningful contributions to the field. With its emphasis on simplicity and accessibility, this book promises to inspire a new wave of research, reignite interest in metallurgy and mechanical engineering, and empower scholars to explore novel applications and contribute to the advancements in this field.
