This book was released on 1978 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies on eutectoid steel have demonstrated that strength and toughness are essentially independently varying parameters, with the former primarily controlled by the pearlite interlamellar spacing and the latter primarily controlled by the prior austenite grain size. The work has now been extended to study the effect of modest compositional variations on strength and toughness of 17 experimental rail alloys. Carbon, manganese, and silicon levels were varied over ranges to yield eutectoid or hypoeutectoid microstructures. Vanadium was added to some of these compositions, primarily as a grain refiner. These steels were heat treated to produce varying austenite grain sizes and a reasonably constant, fine pearlite spacing. Instrumented impact tests on precracked Charpy bars were performed to determine both the dynamic fracture toughness (KId), and the Charpy transition temperature. Tensile tests were used to monitor strength and ductility. Mechanical test data were correlated with observed microstructural variations, particularly the austenite grain size and pearlite spacing as well as fractographic studies of the variation of fracture facet size with austenite grain size. These studies led to a general description of the fracture process in such steels.

This book was released on 2020-04-08 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgy is a field of material science and engineering that studies the chemical and physical behavior of metallic elements, intermetallic compounds, and their mixtures, which are called alloys. These metals are widely used in this kind of engineering because they have unique combinations of mechanical properties (strength, toughness, and ductility) as well as special physical characteristics (thermal and electrical conductivity), which cannot be achieved with other materials. In addition to thousands of traditional alloys, many exciting new materials are under development for modern engineering applications. Metallurgical engineering is an area concerned extracting minerals from raw materials and developing, producing, and using mineral materials. It is based on the principles of science and engineering, and can be divided into mining processes, which are concerned with the extraction of metals from their ores to make refined alloys, and physical metallurgy, which includes the fabrication, alloying, heat treatment, joining and welding, corrosion protection, and different testing methods of metals. Conventional metal forming/shaping techniques include casting and forging, which remains an important processing route. Electrodeposition is one of the most used methods for metal and metallic alloy film preparation in many technological processes. Alloy metal coatings offer a wider range of properties than those obtained by a single metal film and can be applied to improve the properties of the substrate/coating system. This book covers a wide range of topics related to recent advancements in metallurgical engineering and electrodeposition such as metallurgy forming, structure, microstructure properties, testing and characterizations, and electrodeposition techniques. It also highlights the progress of metallurgical engineering, the ferrous and non-ferrous materials industries, and the electrodeposition of nanomaterials and composites.

Available in PDF, EPUB and Kindle. Book excerpt: A laboratory study was conducted on a broad range of compositional variations of chromium-molybdenum steels for application as high-strength, as-rolled rails. A series of experimental heats was prepared and processed to simulate commercial production of as-rolled 65-kg/m (132-lb/yd) rail, with regard to cooling rate and transformation characteristics. Test specimens were evaluated in terms of hardness, tensile properties, and microstructure. The mechanical properties are related to the observed microstructures. Increasing the molybdenum content of the steel is highly effective in increasing yield strength by refining the pearlite; the appearance of coarse bainite reduces the yield strength. Vanadium contributes additional strengthening, but only under certain conditions where the pearlite is refined. Lowering carbon and adding columbium produces microstructural changes that are not beneficial to the mechanical properties. These results make possible some tentative conclusions regarding the optimization of composition for the commercial production of as-rolled rails in the 760 to 1170 N/mm2 (110 to 170 ksi) yield strength range.
Download or read book Effect of Austenitizing Temperature Upon the Microstructure and Mechanical Properties of Experimental Fe written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing the austenitizing temperature from 870°C to 1100°C and higher can increase the fracture toughness, K/sub Ic/, of common high strength structural steels from 50 to 100% with no loss in strength. However, the ductility (% reduction in area from a tensile test) decreases by as much as a factor of 3, and the Charpy impact energy either decreases or remains constant. The trend of increasing fracture toughness and decreasing Charpy impact energy appears to be inconsistent, but has been rationalized by considering the interaction of the stress field as a function of notch root radius and the microstructure. The present study investigates the as-quenched strength and toughness of simple Fe/Cr/C alloys with and without titanium as a function of austenitizing temperature. For the ternary Fe/Cr/C alloys the results are consistent with earlier investigations, but the fracture toughness does not change with increasing austenitizing temperatures after 0.2 wt % Ti is added. The titanium forms carbides (TiC) that did not dissolve, providing a roughly constant number of crack nucleation sites, and preventing austenite grain growth up to 1100°C. The differences in mechanical behavior, particularly the rounded notch toughness, are discussed and explained in terms of the microstructural characteristics of the alloys.
