In 1924, the American Society for Testing and Materials (ASTM) organized the symposium "Corrosion and Heat Resisting Alloys, and Electrical Resistance Alloys." It was the beginning of a major role that ASTM played in the history of stainless steel. This chapter provides information on the papers presented at the 1924 symposium. It also describes the role of ASTM in stainless steel standardization after the 1924 symposium.

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.

This chapter reviews the general principles involved in codifying standards and describes the historical development of materials testing standards. It provides information on the standards related to the Brinell, Vickers, Rockwell, and Knoop methods as well as those for the instrumented indentation test and hardness conversions.

This chapter provides a detailed account of the development of tool steel technology. It begins with a record of steelmaking in ancient and medieval times. The crucible melting process involved in making steel is then discussed. This is followed by a description of the increasing use of alloys for tool steels. The chapter provides information on the research investigations into the metallurgy of high-speed tool steels at MIT, Union Carbide, and Carbon Laboratories. The major research effort involved in substituting molybdenum for tungsten in high-speed tool steels is discussed. The chapter also describes the role of the Cleveland Twist Drill Company as the first adopter of molybdenum high-speed steel. It ends with a discussion on the advanced work on high-speed steels by Swedish researchers.

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 discusses the metallurgical considerations and process requirements of nitriding. It presents the pioneering work of Adolph Machlet and Adolph Fry and presents early developments. One such development is the Floe process, a two-stage treatment used to reduce the formation of a compound layer on the surface of a nitrided steel.

This chapter covers the tribological properties of different types of oil, greases, solid lubricants, and metalworking and traction fluids. It explains how lubricants are made, how they work, and how they are applied and tested. It also discusses the fundamentals of lubrication and friction control, the relationship between viscosity and breakaway friction, and the factors that affect load-carrying capacity and service life.

This chapter briefly describes the early discoveries of the key ingredients of and alloys of stainless steel that occurred in the 18th and 19th centuries and the advancement that happened in the early part of the 20th century. The key ingredient and alloys covered include iron-chromium alloys, acid- and weather-resistant alloy, ferrochromium, martensitic stainless steel, chromium-nickel austenitic stainless steels, and ferritic chromium stainless steel. Information on the early discoverers and pioneers of stainless steel is also provided.

This chapter is a detailed account of the history of development of titanium and its modern applications in the aerospace market. It begins by discussing the attempts made to produce titanium metal. This is followed by a discussion on the invention of a process for making titanium by William Kroll. 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.

This chapter describes some of the technological milestones of the early 20th century, including the invention of tungsten carbide tool steel, the use of age-hardening aluminum in the Wright Flyer , the development of a new heat treating process for aluminum alloys, and Ford’s pioneering use of weight-saving vanadium alloys in Model T cars. It explains how interest in chromium alloys spread throughout the world, spurring the development of commercial stainless steels. The chapter concludes with a bullet point timeline of early 20th century achievements and a brief assessment of more recent innovations.

This chapter covers the early studies and various discoveries by metals researchers to study the internal structure of metals. The topics covered include light microscopy, phase diagrams, X-ray diffraction, principles of precipitation hardening, and dislocation theory.

Diffusion is the movement of atoms through the crystalline lattice. This chapter discusses the two main types of diffusion that can occur in solids: interstitial diffusion and substitutional diffusion. It describes Fick's first and second laws of diffusion, with emphasis on several applications of the latter. The chapter also provides information on the temperature dependence of diffusion, intrinsic diffusion coefficients (Kirkendall effect), and high diffusion paths.

This chapter gives a brief overview of the role of fatigue in component failures. It presents examples of fatigue failures along with statistics on the causes and costs of fatigue damage in various industries. It also includes a chapter-by-chapter summary of the content in the book, noting that the book deals primarily with fatigue at temperatures below the creep range with high-temperature fatigue being treated in a companion publication.

This chapter discusses the development of the nomenclature used to describe the constitution and structure of metals and alloys, particularly the phases observed in the microstructure of steel. It also points out some of the problems with current nomenclature and provides recommendations on how to avoid them.

The formation of martensite is characterized by its athermal transformation kinetics, crystallographic features, and development of fine structure. This chapter describes the diffusionless, shear-type transformation of austenite to martensite and how it affects the morphology and microstructure of heat-treatable carbon steels. It also provides information on lath and plate martensite and how they differ in structure and deformation properties.
