This article provides a discussion on binary alloy phase diagrams published in this handbook. All diagrams presented are for stable equilibrium conditions, except where metastable conditions are indicated.

This article presents ternary alloy phase diagrams to be used primarily by engineers to solve industrial problems. The diagrams presented are for stable equilibrium conditions, with the exception of metastable conditions for some diagrams involving carbon and iron. In some ternary diagrams involving carbon and iron, the symbol M is used to represent both iron and the other metallic element when the two metals substitute for each other in a carbide phase.

This article presents a glossary of terms related to fractography.

This article explains the key features of the manufacturing techniques for polymer composites. It describes the selection of a technically and economically feasible manufacturing technique for a composite design. The article discusses widely accepted and emerging techniques to manufacture polymer composites such as open-mold techniques.

This article presents a glossary of terms related to welding. The terms are arranged in the conventional dictionary letter-by-letter alphabetical sequence.

Titanium has been recognized as an element with good mechanical and physical properties, alloying characteristics, and corrosion resistance. Providing an outline of general characteristics and types of titanium alloys, this article discusses the contemporary technology of titanium along with its market developments. It also discusses the application of titanium and titanium alloys in corrosive environments and in aerospace and automotive industries. The article describes the developments in titanium processing and materials technologies, which include the development of sponge production and melting processes, oxide dispersion-strengthened alloys by powder metallurgy techniques, titanium-base intermetallic compounds, and titanium-matrix composites.

This article summarizes the general classification, mechanical properties, and applications of ferrous powder metallurgy (PM) materials for parts production. It discusses four principal ferrous PM alloy types: admixed elemental alloys, diffusion alloys, prealloys, and hybrid alloys. The article reviews the benefits and disadvantages as well as the effect of processing on the properties and material microstructure of these alloys. It contains tables that list the mechanical properties of various iron-copper and copper steels.
