Download or read book Optimizing Mechanical Properties of Specialty Stainless and Heat Resistant Alloy Steel Forgings by Thermomechanical Processing written by WS. Darden and published by . This book was released on 1986 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferrous alloy forgings typically are used at the critical points in any given application, and thus it is incumbent upon the forger to select optimum melting technology and design processing techniques to provide specialty, stainless, and heat-resistant steels that possess the full extent of the grade's mechanical properties. Thermomechanical processing techniques can be employed to achieve such goals. In specialty steels such as HP310, HP9Ni-4Co-0.20C, and AF1410, combinations of working practices and thermal treatments have been examined to maximize the ductility and/or fracture toughness of these ultra-high strength steels. In stainless steel Grades 15-5PH and PH13-8Mo in forgings, critical fracture-toughness requirements can be enhanced by careful selection of forging parameters. Finally, for heat- and corrosion-resistant materials, including A286 and Inconel 625, relationships between forging and thermal treatments have been studied that optimize grain size, strength, and toughness.

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers a collection of papers summarizing some of the latest developments in the thermomechanical processing of steels. The replacement of conventional rolling plus post-rolling heat treatments by integrated controlled forming and cooling strategies implies important reductions in energy consumption, increases in productivity and more compact facilities in the steel industry. The metallurgical challenges that this integration implies, though, are relevant and impressive developments that have been achieved over the last 40 years. The frequency of the development of new steel grades and processing technologies devoted to thermomechanically processed products is increasing, and their implementation is being expended to higher value added products and applications. In addition to the metallurgical peculiarities and relationships between chemical composition, process and final properties, the relevance impact of advanced characterization techniques and innovative modelling strategies provides new tools to achieve the further deployment of the TMCP technologies. The contents of the book cover low carbon microalloyed grades, ferritic stainless steels and Fe–Al–Cr alloys, medium-Mn steels, and medium carbon grades. Authors of the chapters of this "Thermomechanical Processing of Steels" book represent some of the most relevant research groups from both the steel industry and academia.

Available in PDF, EPUB and Kindle. Book excerpt: Thermo-mechanical simulation studies can be effectively utilized for optimization of processing parameters apart from development of new alloys, quality/yield improvement and material characterization. Physical simulation, being very close to the real world process, can be very helpful in near exact reproduction of the process, and in turn, better results. Thermo-mechanical simulation studies using Gleeble System found extensive applications in steel research and its processing. It can help in careful design of alloy chemistry, proper continuous casting operation to produce defect-free casting, and optimization of hot rolling and post-cooling parameters to produce the desired microstructure and annealing process after cold rolling to achieve the desired microstructure and properties, welding for easy fabrication, etc. Each of these steps needs to be fine-tuned and optimized to achieve the maximum benefit towards reduction in alloy additions, as well as quality and yield improvement during steel processing. A number of studies like continuous casting simulation for production of Cr-alloyed rail steel, hot deformation simulation and phase transformation behavior to optimize hot rolling of difficult to process high boron steel, and hot deformation simulation to bring down the rolling load and annealing simulation to achieve the desired hardness in low nickel stainless steel, etc. undertaken, helped to improve the processing of these steels. Details of these studies, results obtained, and the way to improve processing were discussed.

Book excerpt: Increased strengths can be achieved in precipitation-hardened stainless steels by deforming the steel and retaining a worked structure prior to aging. JBK-75 is one example of a superalloy which will respond to this type of thermomechanical processing. The present study was undertaken to determine the tensile properties of different forged shapes resulting from the combined effects of strain hardening and precipitation hardening. Various size bar stock was deformed by High Energy Rate Forging (HERF) and subsequently aged. Resultant tensile properties were quite variable, showing a wide range of strengths and ductilities, well below expected values. The tensile properties were strongly dependent upon forging geometry.

Available in PDF, EPUB and Kindle. Book excerpt: Stainless steels represent a quite interesting material family, both from a scientific and commercial point of view, following to their excellent combination in terms of strength and ductility together with corrosion resistance. Thanks to such properties, stainless steels have been indispensable for the technological progress during the last century and their annual consumption increased faster than other materials. They find application in all these fields requiring good corrosion resistance together with ability to be worked into complex geometries. Despite to their diffusion as a consolidated materials, many research fields are active regarding the possibility to increase stainless steels mechanical properties and corrosion resistance by grain refinement or by alloying by interstitial elements. At the same time innovations are coming from the manufacturing process of such a family of materials, also including the possibility to manufacture them starting from metals powder for 3D printing. The Special Issue scope embraces interdisciplinary work covering physical metallurgy and processes, reporting about experimental and theoretical progress concerning microstructural evolution during processing, microstructure-properties relations, applications including automotive, energy and structural.
