Description And Engineering Characteristics Of Eleven New High Temperature Alloys

The Memorandum contains a description and summary of preliminary properties of eleven new alloys that are considered to be promising high-temperature materials. Most of them are in the experimental-application stage of their development; however, a few have reached the point where they can be considered commercial. Included are six nickel-base alloys, two iron-base alloys, one iron-nickel-base alloy, one cobalt base alloy, and one multicomponent alloy that contains primarily nickel and chromium. Following descriptions of composition and microstructure of each alloy, a large section of the memorandum is concerned with physical and mechanical properties, predominantly stress-rupture and creep properties. Oxidation and sulfidation as well as elevated temperature stability of the alloys is discussed. Information on processing and availability of the alloys is also given. (Author).

Editors Altan (Ohio State University), Ngaile (North Carolina University), and Shen (Ladish Company, Inc.) offer this extensive overview of the latest developments in the design of forging operations and dies. Basic technological principles are briefly reviewed in the first two chapters.

The handbook provides design engineers with up-to-date information about the many aspects of forging including descriptions of important developments made more recently by industry and/or government. The handbook describes suitable measures for in-process quality control and quality assurance, summarizes relationships between forging practices and important mechanical properties and compares various forging devices to aid in equipment selection. Attention is also given to describing practices for relatively new materials and emerging forging practices. (Modified author abstract).

If you are involved with machining or metalworking or you specify materials for industrial components, this book is an absolute must. It gives you detailed and comprehensive information about the selection, processing, and properties of materials for machining and metalworking applications. They include wrought and powder metallurgy tool steels, cobalt base alloys, cemented carbides, cermets, ceramics, and ultra-hard materials. You'll find specific guidelines for optimizing machining productivity through the proper selection of cutting tool materials plus expanded coverage on the use of coatings to extend cutting tool and die life. There is also valuable information on alternative heat treatments for improving the toughness of tool and die steels. All new material on the correlation of heat treatment microstructures and properties of tool steels is supplemented with dozens of photomicrographs. Information on special tooling considerations for demanding applications such as isothermal forging, die casting of metal matrix composites, and molding of corrosive plastics is also included. And you'll learn about alternatives to ferrous materials for metalworking applications such as carbides, cermets, ceramics, and nonferrous metals like aluminum, nickel, and copper base alloys.
