This book was released on 1993-07-31 with total page 476 pages. Available in PDF, EPUB and Kindle. 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.

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.

This book was released on 1978 with total page 2 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2017 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research is mostly planned to enhance the fatigue properties of PM steels inasmuch as they are extensively replacing their equivalent wrought steels due mostly to production cost benefits. This goal is going to be achieved through determining the most effective microstructure of PM steels in cyclic loadings. The most effective microstructure is the one that can reduce or stop the fatigue crack propagation through the proper combination of its constituent phases. There exists some researches on this topic, however, they did not reach consistent conclusions due to the lack of sufficient data and/or improper comparison. Therefore, the effect of different constituent phases of a heterogeneous microstructure of a PM steel is still ambiguous and unknown. In order to study this issue, diverse microstructures and the fatigue crack propagation behaviour through them should be studied. Our research begins by choosing two common PM steels manufactured using two alloying techniques of admixed and pre-alloyed to produce heterogeneous and homogeneous microstructures respectively. Two types of heat-treatments namely sinter-hardening and oil-quenching were also utilized to provide more microstructural phases that is needed for the purpose of this study. The samples were then tested in cycling loading using different R-ratio in order to study the effect of fatigue conditions as well. Quantitative analysis of the fracture surfaces, which includes the detailed study of the crack path in OM and SEM, were then performed on the fractured samples. The fatigue crack growth rate data in different PM steels having different microstructures along with the quantitative data acquired from their crack path led us to interesting results on the effect of microstructural constituents on fatigue crack propagation behaviour. It was found that the fatigue crack will propagate more rapidly through the weakest i.e. lowest strength phase among the ones present in the microstructure. Thus, pearlite was not favourable for crack propagation in the company of Ni-rich ferrite while in the presence of martensite, pearlitic grains were found to be the preferred crack path. Moreover, the retained austenite, which was identified in literature to be a beneficial phase for fatigue crack retardation, was found to be ineffective on the matter. Although fatigue cracks circumvented these regions, the deflection caused by this change of crack path did not show any positive effect on fatigue crack retardation.

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.
