Download or read book The Relationship of Microstructure to Strength and Toughness in High-strength Steel written by John Henry Bucher and published by . This book was released on 1965 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the relationship of elements of microstructure to the fracture characteristics of a group of commercially produced steels, heat-treated to ultra-high strength levels. The microstructures were characterized in terms of optical microscopy, electron diffraction, and electron fractography. Fractographic studies were made of fractured surfaces broken in impact at +25 and -196 C as a function of tempering temperature, in slow bending at ambient temperature, in a modified bend test in which slow and fast propagation stages were effected, and on surfaces produced in tensile fractures. The fracture characteristics were studied by means of an instrumented bend test and in terms of the plastic instability generated in the torsion test. The instrumented bend test yielded data on criteria for the onset of slow crack propagation and for the onset of rapid propagation, including the effect of the total stored energy in the system. Plastic instability in torsion was studied as a function of specimen section size in AISI 4340 steel. A 250,000 psi yield strength Maraging steel was studied in a standard size test bar. (Author).

Download or read book Microstructure and Mechanical Properties of Structural Metals and Alloys written by Andrey Belyakov and published by MDPI. This book was released on 2019-06-24 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers collected in this special issue clearly reflect the modern research trends in materials science. These fields of specific attention are high-Mn TWIP steels, high-Cr heat resistant steels, aluminum alloys, ultrafine grained materials including those developed by severe plastic deformation, and high-entropy alloys. The major portion of the collected papers is focused on the mechanisms of microstructure evolution and the mechanical properties of metallic materials subjected to various thermo-mechanical, deformation or heat treatments. Another large portion of the studies is aimed on the elaboration of alloying design of advanced steels and alloys. The changes in phase content, transformation and particle precipitation and their effect on the properties are also broadly presented in this collection, including the microstructure/property changes caused by irradiation.
Book Synopsis A Transmission Electron Microscopy Study of Some High Strength Plain Carbon Steels by : George Joseph Vytanovych

This book was released on 1967 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Methods of preparing foils of high strength, heat treated, plain carbon steels for examination in the electron microscope by the transmission technique were perfected and are described. Two processes for the initial thinning of a bulk sample were successful. A chemical process was found to be more rapid but not satisfactory for small samples. A mechanical process was slower, but was applicable to the smaller specimens. Electro-polishing the thinned material yielded acceptable foils from which photomicrographs of good quality were obtained. The microstructure of the high strength steel samples showed typical tempered martensite. No reasons for the differences in ductility of different heats of steel or for the differences in ductility of a given steel, when heat treated differently, were found"--Abstract, leaf ii.'

This book was released on 1965 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of a number of 0.30 and 0.40 per cent carbon alloy steels to determine the relationships between their fracture toughness properties and their internal microstructures. The plane-strain fracture toughness of the steels was measured after tempering quenched material in the temperature range 300 to 1100 F. A thin section transmission electron microscopy study was carried out on the tempered materials. From the fracture toughness studies it was concluded that all the materials behaved similarly and that alloying elements (carbon and silicon) had little influence on the general relationship between tensile strength and toughness in these fully hardenable steels. It was found that the fracture toughness remained low at low tempering temperatures but improved rapidly once a critical tempering temperature, characteristic of the particular steel, was reached. The microscopy study showed that major microstructural changes occurred in the tempering range where the rapid increase in toughness was observed. At low tempering temperatures the defect structure of the as-quenched martensite remained unchanged, and continuous films of carbide were formed in the boundaries of the martensite. In the critical tempering range the carbide films were spheroidized and the defect structure of the matrix removed or modified by recovery processes. On the basis of these observations, it was concluded that the low fracture toughness of the steels in a lightly tempered condition was due to their high defect densities and the presence of carbide films at boundaries. Only when these features were removed or modified did toughness increase.

This book was released on 2014 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of steel dates back to the 17th century and has been instrumental in the betterment of every aspect of our lives ever since, from the pin that holds the paper together to the Automobile that takes us to our destination steel touch everyone every day. Path breaking improvements in manufacturing techniques, access to advanced machinery and understanding of factors like heat treatment, corrosion resistance have aided in the advancement in the properties of steel in the last few years. In this dissertation document the results of a study aimed at the influence of alloy chemistry, processing and influence of the quasi static and fatigue behavior of seven alloy steels is discussed. The microstructure of the as-received steel was examined and characterized for the nature and morphology of the grains and the presence of other intrinsic features in the microstructure. The tensile, cyclic fatigue and bending fatigue tests were done on a fully automated closed-loop servo-hydraulic test machine at room temperature. The failed samples of high strength steels were examined in a scanning electron microscope for understanding the fracture behavior, especially the nature of loading be it quasi static, cyclic fatigue or bending fatigue. The quasi static and cyclic fatigue fracture behavior of the steels examined coupled with various factors contributing to failure are briefly discussed in light of the conjoint and mutually interactive influences of intrinsic microstructural effects, nature of loading, and stress (load)-deformation-microstructural interactions.
