Metallurgical Developments In High Alloy Steels

Research and development in the field of high-strength stainless steels appears to be directed along two principal paths: (1) the development of alloys with improved strength properties and (2) the accumulation of information on the properties and physical metallurgy of existing alloys so that they may be used more effectively. By and large, the development of new alloys is being carried out by the stainless-steel producers, while the accumulation of property data for the most part is being undertaken on Government contracts.

This report presents information on the physical metallurgy, chemical composition, mechanical and physical properties, corrosion resistance, fabrication, and cleaning of several of the newer high-strength stainless steels. The alloys covered include one semiaustenitic precipitation-hardenable stainless steel, PH14-8Mo, and the following martensitic precipitation- hardenable stainless steels: PH13-8Mo, 15-5PH, Custom 455, AM-363, AM-362, and AFC-77. Also included is 17-4PH as a sheet and strip product.

STEELS: Metallurgy and Applications provides a metallurgical understanding of commercial steel grades and the design, manufacturing and service requirements that govern their application. The properties of different steels are described, detailing the effect of composition, processing and heat treatment. Where appropriate an introduction is given to standard specifications and design codes provided on component manufacture and property requirements for successful service performance. The book deals with steel products in some depth, in four chapters covering wide strip, structural steels, engineering and stainless steel grades. At the begining of each chapter an overview is given which details important features of the grades and a historical perspective of their development. Also featured are up to date information on steel prices and specifications. David Llewellyn has over thirty years experience in the steel industry and is currently lecturing in the Materials Engineering Department at University College Swansea. '..the book unfolds into an easily readable and a valuable source of highly relevant and contemporary information on steels' - METALS AND MATERIALS '.. a high quality product from all points of view' - INSTITUTE OF METALS AND MATERIALS AUSTRALASIA features up to date information on steel prices and specifications.

Specialty Steels and Hard Materials covers the proceedings of the International Conference on Recent Developments in Specialty Steels and Hard Materials (Materials Development '82). The main focus of the materials in the selection is on the microstructural detail, alloy design, processing technology, applications, and economic viability. The first part of the title presents the invited papers in the conference; this part includes topics such as toughness in high speed steels and hard metals; the use of vanadium in low alloy structural steels; and design of strong, ductile, duplex low alloy steels. The second part of the text covers topics about high strength low alloy steels, stainless steels, and rapid solidification processing. The last part of selection deals with tungsten carbide-cobalt hard metals, non-oxide ceramics, and sintered polycrystalline ultra-hard materials. The book will be of great interest to students, researchers, and practitioners of materials engineering and metallurgy.

The book briefly describes the structure, properties and applications of various grades of steel, primarily aimed at non-metallurgical students from other engineering streams. The book consists of nine chapters covering most of the important types of steels and their physical metallurgy, microstructure and engineering applications including iron-carbon diagram, heat treatment, surface hardening methods, effect of alloying, specific applications, selection of materials, case studies and so forth. The book also contains subjective and objective questions aimed at exam preparation. Key Features Exclusive title aimed at introduction to steels for non-metallurgy audience Includes microstructure, composition, and properties of all the most commonly used steels Describes the heat treatments and the required alloying additions to process steel for the intended applications Discusses effects of alloying elements on steel Explores development of steels for specialized areas such as the automobile, aerospace, and nuclear industries
