This data set contains approximately 50 growth curves for a wide range of aluminum casting alloys at various temperatures. Growth curves are used to determine the dimensional changes that must be anticipated during service in applications where close dimensional tolerances are required. Hardness curves are provided for many of the alloys. The hardness values are from corresponding aging response studies in which measurements were made on individual lots considered representative of the respective alloys and tempers.

This chapter examines the properties, structure, and applications of wood and wood products, including plywood, paper, and cardboard. It discusses the dimensional changes that occur due to moisture content and compares several types of wood based on radial and tangential shrinkage.

Distortion is defined as an irreversible and usually unpredictable dimensional change in a component due to thermal processing or temperature variations and loading in service. This chapter describes two types of distortion: size distortion and shape distortion. It addresses how distortion can be managed by controlling certain factors. The chapter discusses the cause and effect of distortion during nitriding, the processes involved in stock removal prior to nitriding, and the criteria for post-machining operations.

This chapter presents an overview of some of the major causes of tool and die failures. The chapter describes fracture and fracture toughness of tool steels, and the influence of factors such as steel quality and primary processing, mechanical design, heat treatment, grinding and finishing, and distortion and dimensional change.

This chapter discusses the methods by which stainless steel powders are shaped and compacted prior to sintering, including rigid die compaction, metal injection molding, extrusion, and hot isostatic pressing. It explains where each process is used and how processing parameters, such as temperature and pressure, and powder characteristics, such as particle size and shape, influence the quality of manufactured parts. It describes the various stages of metal powder compaction, the role of lubricants, and how to account for dimensional changes in the design of tooling and process sequences.
