Uranium alloys are used in applications requiring dense metals, but they have little resistance to oxidation and corrosion and are susceptible to environmentally assisted cracking, particularly when processed to high strength levels. This chapter describes the conditions under which uranium alloys are most prone to cracking. It discusses testing and characterization methods, cracking phenomenology, material properties, and microstructure. It also provides suggestions for avoiding and overcoming environmentally assisted cracking problems.

Nonferrous metals are of commercial interest both as engineering materials and as alloying agents. This chapter addresses both roles, discussing the properties, processing characteristics, and applications of several categories of nonferrous metals, including light metals, corrosion-resistance alloys, superalloys, refractory metals, low-melting-point metals, reactive metals, precious metals, rare earth metals, and metalloids or semimetals. It also provides a brief summary on special-purpose materials, including uranium, vanadium, magnetic alloys, and thermocouple materials.

This chapter discusses the characteristics of eutectoid transformations, a type of solid-state transformation associated with invariant reactions, focusing on the iron-carbon system of steel. It describes the compositions, characteristics, and properties of ferrite, eutectoid, hypoeutectoid, and hypereutectoid structures and how they are affected by the addition of various alloying elements. The chapter also discusses the formation of peritectoid structures in the uranium-silicon alloy system.

This appendix contains symbols for some common elements applicable to tribosystems.

This chapter is a compilation of beryllium phase diagrams, representing more than 25 binary alloy systems from beryllium-aluminum to beryllium-zirconium. Each diagram is presented along with a summary and source reference.

This chapter covers regulatory requirements, safe handling practices, hazard analysis and control, dismantling and decommissioning, and waste disposal. It also includes references for additional information on government regulations.

This appendix lists plating solutions and procedures used in metallographic edge preparation.

This appendix contains a table listing the symbol, atomic number, atomic weight, melting temperature, density, atomic radius, and crystal structure of various elements.
