High Temperature Alloys by J.B. Marriott,M. Merz,J. Nihoul,Ian M. Ward Pdf

Advances in industrial technologies and improved performance of constructional materials are interdependent and have become of increasing concern in recent years. This Conference aimed to - provoke discussion of the limits towards which high temperature alloys properties can, ultimately, be developed, identify the resulting R&D requirements and design developments. Following a key-note paper concerning the relation of current capabilities to requirements for gas turbines the conference was structured into 3 sessions which examined: * the theoretical?ldpracticallimits for HT Alloys, * the potential for development in alloys and processing, * engineering considerations. Finally, feeling perhaps the approaching "wind of change"??1s Conference on remaining alloy potential was wound up with a paper entit1ed "The potential?ld problems ofEngineering Ceramics". The different sessions each included a number of invited papers followed by a series of posters and were concluded by a presentation of a "synthesis" by a sess10n rapporteur and general discussion. This structure is retained in the proceedings, including the discussion points in those cases where?le authors have provided written answers to questions raised.

The Role of Active Elements in the Oxidation Behaviour of High Temperature Metals and Alloys by E. Lang Pdf

Metals and alloys rely for their application at high temperature on the formation and retention of oxide scales, which act as a barrier between the metallic substrate and the reactive species in the environment such as 0, S, N, C, Cl, etc. This protection concept requires that the oxide grows slowly, develops a dense, uniform layer, is well adherent, has sufficient ductility to accom modate plastic deformation of the substrate and is resistant to thermal cycling. For many years it has been known that small concentrations of certain "active elements" such as Y and the rare earths, as well as carbon and sulphur, can exercise a significant influence upon the oxidation! corrosion behaviour of high temperature metals and alloys. An increasing number of experimental studies on this topic have been published recently. However no generally accepted understanding with regard to the detailed mechanisms and the way in which alloy composition and structure, temperature and environmental conditions, etc., are interacting has yet been achieved, although many - often controversial - theories and ideas have been presented. It therefore seemed to be an appropriate time to bring together a group of experts to review and evaluate the current state-of-the-art and to discuss various aspects of this important topic.

High Temperature Oxidation and Corrosion of Metals by David John Young Pdf

The book is concerned with understanding the fundamental mechanisms of high temperature alloy oxidation. It uses this understanding to develop methods of predicting oxidation rates and the way they change with temperature, gas chemistry and alloy composition. The focus is on designing (or selecting) alloy compositions which provide optimal resistance to attack by corrosive gases. . Emphasises quantitative calculations for predicting reaction rates and the effects of temperature, oxidant activities and alloy compositions. . Uses phase diagrams and diffusion paths to analyse and interpret scale structures and internal precipitation distributions . Provides a detailed examination of corrosion in industrial gases (water vapour effects, carburisation and metal dusting, sulphidation) . Text is well supported by numerous micrographs, phase diagrams and tabulations of relevant thermodynamic and kinetic data . Combines physical chemistry and materials science methodologies.

High-temperature Property Data by Michael F. Rothman,ASM International Pdf

This volume organizes information by alloy so that pertinent data can be found easily. Physical and mechanical properties from room temperature to temperatures in excess of 100 C are shown graphically or in tabular form. All data is thoroughly referenced. Now high-temperature property data can be found in one complete reference! Over 200 alloys are organized by AISI number into 11 major sections: Irons, Carbon Steels, Alloy Steels, ASTM Steels, Low Alloy Constructional Steels, Ultra High Strength Steels, Tool Steels, Maraging Steels, Wrought Stainless Steels, Heat Resistant Casting Alloys, and Wrought Iron-Nickel Alloys and Iron-Nickel Superalloys. Each alloy record lists the designation, specifications, UNS number composition product forms and a comment on the high-temperature properties and applications. Data is then given for physical properties such as density, specific heat, thermal conductivity, thermal expansion, electrical conductivity. Poisons ratio, moduli of elasticity and rigidity, etc. Mechanical properties follow, and include tensile properties, shearing and bearing properties, impact properties, creep, stress rupture and stress relaxation, and fatigue properties.The last part of the alloy record gives other effects of temperature, such as hot hardness, corrosion, and growth.

High-Temperature Corrosion and Materials Applications by George Y. Lai Pdf

George Lai's 1990 book, High-Temperature Corrosion of Engineering Alloys, is recognized as authoritative and is frequently consulted and often cited by those in the industry. His new book, almost double in size with seven more chapters, addresses the new concerns, new technologies, and new materials available for those engaged in high-temperature applications. As we strive for energy efficiency, the realm of high-temperature environments is expanding and the need for information on high temperature materials applications was never greater. In addition to extensive expansion on most of the content of the original book, new topics include erosion and erosion-corrosion, low NOx combustion in coal-fired boilers, fluidized bed combustion, and the special demands of waste-to-energy boilers, waste incinerators, and black liquor recovery boilers in the pulp and paper industry. The corrosion induced by liquid metals is discussed and protection options are presented.

High Temperature Strain of Metals and Alloys by Valim Levitin Pdf

Creep and fatigue are the most prevalent causes of rupture in superalloys, which are important materials for industrial usage, e.g. in engines and turbine blades in aerospace or in energy producing industries. As temperature increases, atom mobility becomes appreciable, affecting a number of metal and alloy properties. It is thus vital to find new characterization methods that allow an understanding of the fundamental physics of creep in these materials as well as in pure metals. Here, the author shows how new in situ X-ray investigations and transmission electron microscope studies lead to novel explanations of high-temperature deformation and creep in pure metals, solid solutions and superalloys. This unique approach is the first to find unequivocal and quantitative expressions for the macroscopic deformation rate by means of three groups of parameters: substructural characteristics, physical material constants and external conditions. Creep strength of the studied up-to-date single crystal superalloys is greatly increased over conventional polycrystalline superalloys. From the contents: - Macroscopic characteristics of strain at high temperatures - Experimental equipment and technique of in situ X-ray investigations - Experimental data and structural parameters in deformed metals - Subboundaries as dislocation sources and obstacles - The physical mechanism of creep and the quantitative structural model - Simulation of the parameters evolution - System of differential equations - High-temperature deformation of industrial superalloys - Single crystals of superalloys - Effect of composition, orientation and temperature on properties - Creep of some refractory metals For materials scientists, solid state physicists, solid state chemists, researchers and practitioners from industry sectors including metallurgical, mechanical, chemical and structural engineers.
