Book Description
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.

Book Description
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.

Book Description
THIS REPORT IS MAINLY CONCERNED WITH FORGINGS MADE FROM MARTENSITIC STEELS HEAT TREATED TO STRENGTHS RANGING FROM 240,000 TO 300,000 PSI. FORGING CHARACTERISTICS, DESIGN LIMITATIONS, DIMENSIONAL TOLERANCES, AND QUALITY-CONTROL PROBLEMS ARE DISCUSSED. A CONSIDERABLE AMOUNT OF DATA ON MECHANICAL PROPERTIES IS ALSO PRESENTED. IN ADDITION, THE REPORT SUMMARIZES THE AVAILABLE INFORMATION ON FORGED, SEMIAUSTENITIAL STEELS. THIS COMPILATION IS BASED ON PUBLISHED ARTICLES, GOVERNMENT REPORTS, AND INTERVIEWS WITH PRODUCERS AND USERS OF STEEL FORGINGS.
