This appendix contains a list of Greek letters used in materials science and engineering and what they represent.

This chapter contains tables providing reference information on physical constants, unit symbols, SI prefixes, the Greek alphabet, and the unit conversion table.

Steels are over 95% Fe, so a good starting point for understanding steel is to study the nature of solid iron. This chapter provides information on the composition, phase transformation, and associated changes in the crystal structure of pure iron at varying temperatures.

This chapter describes the physical characteristics, properties, and behaviors of solid solutions under equilibrium conditions. It begins with a review of a single-component pure metal system and its unary phase diagram. It then examines the solid solution formed by copper and nickel atoms. It discusses the difference between interstitial and substitutional solid solutions and the factors that determine the type of solution that two metals are likely to form. It also addresses the development of intermediate phases, the role of free energy, transformation kinetics, liquid-to-solid and solid-state phase transformations, and the allotropic nature of metals.
