This chapter provides a brief review of the scientific and technological developments leading to the widespread use of induction heat treating and its many applications in industry.

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 discusses the evolution of engineering alloy steels, namely chromium, nickel, and nickel-chromium alloy steels. The discussion includes the automotive demand and development of specifications for the alloy steels. It also covers various research on heat treatment of alloy steels, providing information on hardening, transformation of austenite, hardenability testing, and tempering of as-quenched martensite.

This chapter describes the origins of solders and soldering, covering the composition of solders and applications of soldering.

This chapter briefly reviews the history of brazing from ancient times to the early 20th century.

This chapter traces the history of steelmaking over three millennia, from the discovery of martensite in a mining tool dating from the twelfth century B.C. to the nineteenth century development of the Bessemer and Siemens processes. It also describes the work of early metallographers who discovered many phases and microstructures associated with steel and gave them their now familiar names. The chapter concludes with a brief discussion on the emergence of continuous casting and the subsequent development of strip casting production techniques.

This chapter provides an overview of the production and use of titanium and its significance as an engineering material. It begins by identifying important deposits and ores and assessing current and future production capacities and how they align with global consumption trends. It then describes the physical and mechanical properties of pure titanium and numerous grades of wrought titanium alloys and explains how they compare with other aerospace materials in terms of processing complexity and cost. The chapter also includes information on extractive metallurgy, current and emerging processes, product forms, and related costs.

This chapter presents a brief description of the three-step process: melting, decarburizing, and alloying. It also discusses the following processes: wild process, rustless process, and Linde Argon-Oxygen decarburization process.

This appendix features images from the front and back covers and inside the covers of the book The History of Stainless Steel .

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

This chapter presents a brief review of the history of brazing and soldering. It illustrates complicated soldering techniques and masterful goldsmith work, as demonstrated by the famous gold mask of the Egyptian Pharaoh Tutankhamun. The chapter includes the image of a painting from Egypt circa 1475 B.C. that shows a goldsmith soldering with a blowpipe. Numerous similar images have been found in the tombs of ancient Egypt that offer insight into the practices of gold workers from the period, including the use of processes such as smelting, forging, and joining with both brazing and soldering.
