Superalloys: A Technical Guide, Second Edition provides practical information on the selection, processing, use, and analysis of superalloys. It covers nearly every aspect of these materials including composition, microstructure, properties, phases, alloying, and strengthening mechanisms as well as manufacturing-related processes such as melting, casting, forging, forming, powder metallurgy, heat treating, welding, brazing, machining, cleaning, and surface finishing. The book also discusses the effects of corrosion and overheating, describes testing methods, and includes property and performance data for many wrought and cast nickel-, cobalt-, and iron-nickel-base alloys.

Titanium: A Technical Guide, Second Edition provides a review of the significant features of the metallurgy and application of titanium and its alloys. All technical aspects of the use of titanium are covered, with sufficient metals property data. The book begins with an introduction and then covers selection of titanium alloys, metallurgy of titanium, ingot metallurgy and mill products, forging and forming, castings, powder metallurgy, heat treating, joining, machining, cleaning and finishing, properties, and corrosion resistance. Appendices include additional reference tables and datasheets for the most important commercial grades of titanium and titanium alloys.

This chapter intends to create a sufficient understanding of titanium and its alloys so that selection of them for specific designs will be appropriate. It provides the user with sufficient knowledge to ask the important technical questions of titanium alloy and product providers. Titanium has two elemental crystal structures: in one, the atoms are arranged in a body‐centered‐cubic (bcc) array; in the other they are arranged in a hexagonal close‐packed (hcp) array. Appropriate compositions of all titanium alloys can be forged, rolled to sheet, or otherwise formed into a variety of shapes. Fabricated structures may contain cast as well as wrought parts although wrought parts are assembled in most applications. Single‐piece forged gas turbine fan and compressor disks are prime applications for titanium alloys. Titanium aluminides have been the subject of multidecades of consideration with interesting but limited economically viable results.

This chapter intends to create a sufficient understanding of superalloys so that selection of them for specific designs will be appropriate. The nature of superalloys is that they resist the creep rupture process better than other materials, have very good higher temperature short‐time strength (yield, ultimate) and fatigue properties (including fatigue crack propagation resistance), and combine these mechanical properties with good to exceptional oxidation resistance. The density, melting point, and physical properties of the superalloy base elements are given in the chapter. Superalloy melting practices may be classified as either primary (the initial melt of elemental materials and/or scrap which sets the composition) or secondary (remelt of a primary melt for the purpose of controlling the solidification structure). The principal casting practice for superalloy components is investment casting. Some sources of superalloy expertise in ingot melting, component forging, and article casting are listed in the chapter.
