This appendix is a collection of tables listing the chemical compositions of wrought ferritic steels; wrought stainless steels; cast corrosion- and heat-resistant alloys; wrought iron-, nickel-, and cobalt-base alloys; cast nickel- and cobalt-base alloys; oxide-dispersion-strengthened alloys; and iron-, nickel- and cobalt-base filler metals.

This article reviews weldability of aluminum alloys and factors that affect weld performance. It first addresses hot tears, which can form during the welding of various aluminum alloys. It then presents comparison data from different weldability tests and discusses the specific properties that affect welding, namely oxide characteristics; the solubility of hydrogen in molten aluminum; and its thermal, electrical, and nonmagnetic characteristics. The article addresses the primary factors commonly considered when selecting a welding filler alloy, namely ease of welding or freedom from cracking, tensile or shear strength of the weld, weld ductility, service temperature, corrosion resistance, and color match between the weld and base alloy after anodizing. A number of factors, both global and local, that influence the fatigue performance of welded aluminum joints are also covered.

This chapter describes the factors that affect the corrosion performance of aluminum assemblies joined by methods such as welding, brazing, soldering, and adhesive bonding. The factors covered include galvanic effects, crevices, and assembly stresses in products susceptible to stress-corrosion cracking.

The nonferrous alloys described in this chapter include aluminum and aluminum alloys, copper and copper alloys, titanium and titanium alloys, zirconium and zirconium alloys, and tantalum and tantalum alloys. Some of the factors that affect the corrosion performance of welded nonferrous assemblies include galvanic effects, crevices, assembly stresses in products susceptible to stress-corrosion cracking, and hydrogen pickup and subsequent cracking. The emphasis is placed on the compositions, general welding considerations, and corrosion behavior of these alloys.

This chapter considers the role of materials in brazing operations and the manner in which they impact on the choice of processing conditions and their optimization. The concepts covered are metallurgical and mechanical constraints, and constraints imposed by the components and their solutions as well as service environment considerations.

This chapter considers the materials and processing aspects of soldering and the manner in which these interrelate in the development of joining processes. It discusses the processes involved in eliminating or suppressing metallurgical and mechanical constraints as well as constraints imposed by the components.

This chapter discusses some of the metallurgical factors that affect corrosion of weldments and describes a few considerations for selected nonferrous alloy systems: aluminum, titanium, tantalum, and nickel.

This chapter discusses the processes involved in the wetting, spreading, and chemical interaction of a braze on a nonmetal. The chapter reviews the key materials and process issues relating to the joining of nonmetals using active brazing. Emphasis is placed on the differences in brazing to metals by established methods. The chapter also describes the designing process and properties of metal/nonmetal joints.
