Various studies on the properties on titanium and research programs related to the production of titanium sponge and titanium metal products are then described. The chapter concludes with a discussion of titanium use in jet engines.

Engineers have many materials to choose from when dealing with weight-related design constraints. The list includes aluminum, beryllium, magnesium, and titanium alloys as well as engineering plastics, structural ceramics, and polymer-, metal-, and ceramic-matrix composites. This chapter provides a brief overview of these lightweight materials, discussing their primary advantages along with their properties, behaviors, and limitations.

This appendix provides information on organizations that issue specifications and standards related to titanium and its alloys.

This chapter covers the biographies and literary and research work of pioneers in metals research, namely Henry Marion Howe, Albert Sauveur, Isaiah (Zay) Jeffries, Paul Dyer Merica, Edgar C. Bain, Samuel Leslie Hoyt, and Francis L. VerSnyder.

Integrated computational materials engineering (ICME) is a novel approach to design, develop, and deploy materials. This chapter presents ICME and the development of third generation advanced high-strength steels.

A product pedigree describes its design and how it was built and shows that it was built in accordance with the drawings and other documentation defining the product configuration. Evaluating the pedigree of a failed product can help to rule in or rule out hypothesized failure causes. This chapter describes various areas that can be examined by the failure analysis team to assess the pedigree of the failed system. If the failure analysis team suspects product pedigree anomalies it should confirm conformance through independent means.

This chapter describes some of events and developments that helped drive the commercialization of beryllium and its acceptance as an engineering material. It traces the growth of the domestic beryllium industry from its origins in the 1920s to the present time, and provides a status update on the primary beryllium producers throughout the world.

This chapter provides a brief history of powder metallurgy from its earliest known uses to present day applications.

Critical process variables must be controlled to ensure uniform and repeatable heat-treating results. This chapter covers the subject of controlling the heat-treating process. All heat-treating equipment utilizes various sensors, timers, and other components to monitor and control the process utilizing various control methods. The chapter focuses on temperature control and measurement, including a discussion about thermocouples and devices for measuring thermal and electrical conductivity.

This chapter gives a brief review of the development of additive manufacturing (AM) and the appeal of different of different AM methods.

Cold spray is a process technology that, for the first time, enables the rapid deposition of a wide range of metals and some other materials in the solid state at temperatures far below their melting points. This chapter provides an overview of the processes involved in cold spray process technologies, namely high-pressure cold spray (HPCS) and low-pressure cold spray (LPCS), explaining differences of LPCS from HPCS. It summarizes the historical background of the cold spray process. The growing international interest in the cold spray process from the early 2000s is also reviewed.
