Book Description
The design of new alloys or metal-based composites as well as the optimization of any of the processes involved in high-temperature deformation must take into account the characterization and/or modeling of the high-temperature mechanical responses of the material. This is not a new concept. Nevertheless, there is still much to be done both in terms of data accumulation, specifically for innovative materials, and in terms of material modeling for proper process management, specifically when innovative deformation processes, including more complex time and temperature combinations, are considered. Microstructural changes induced by the process can also severely affect both the further processability of the material as well as its final properties (structural or functional). Similar considerations hold in the case of conventional or innovative metallic materials, where high-temperature deformation occurs due to high-temperature service of the structural components. Thus, knowledge of the effects on the initial microstructure as well as the microstructural changes taking place during in-service deformation are of paramount importance for the optimization of high-temperature structural alloys. This book 'High-Temperature Behavior of Metals' contains contributions dealing with a wide range of metallic materials, illustrating some of the most recent and interesting advances in the field of the high-temperature structural behavior of metallic materials.

Book Description
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.

Book Description
This monograph presents approaches to characterize inelastic behavior of materials and structures at high temperature. Starting from experimental observations, it discusses basic features of inelastic phenomena including creep, plasticity, relaxation, low cycle and thermal fatigue. The authors formulate constitutive equations to describe the inelastic response for the given states of stress and microstructure. They introduce evolution equations to capture hardening, recovery, softening, ageing and damage processes. Principles of continuum mechanics and thermodynamics are presented to provide a framework for the modeling materials behavior with the aim of structural analysis of high-temperature engineering components.

Book Description
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.

Book Description
In recent years, cognitive and affective science have become increasingly important for interpretation and explanation in the social sciences and humanities. However, little of this work has addressed American literature, and virtually none has treated national identity formation in influential works since the Civil War. In this book, Hogan develops his earlier cognitive and affective analyses of national identity, further exploring the ways in which such identity is integrated with cross-culturally recurring patterns in story structure. Hogan examines how authors imagined American identity—understood as universal, democratic egalitarianism—in the face of the nation’s clear and often brutal inequalities of race, sex, and sexuality, exploring the complex and often ambivalent treatment of American identity in works by Charlotte Perkins Gilman, Eugene O’Neill, Lillian Hellman, Djuna Barnes, Amiri Baraka, Margaret Atwood, N. Scott Momaday, Spike Lee, Leslie Marmon Silko, Tony Kushner, and Heidi Schreck.
