This book does not aspire to discuss pure materials science topics, nor to offer comprehensive numerical design data for each material, although reference is made to underlying materials science concepts wherever opportune. It does, however, seek to identify those parameters which must be considered when selecting materials for use in engineering applications. Emphasis is put on the needs of manufacturing industry, which is defined for present purposes as involved in production of prefabricated parts and components intended for civil, domestic, marine, military, aerospace and chemical processing applications. The decision has been taken to omit all aspects of the building and construction industry, so no reference is made to concrete, timber, bitumens, soil and masonry.

The chapter on the impact of design on manufacturing industry is intended to demonstrate how correct selection of materials in terms of their performance, availability and cost, together with exploitation of available production capability, will enhance the profitability of a commercial operation.

Having embarked upon a design study, it is necessary for the expertise and judgement of the design engineer to be coordinated with those of other experts to produce the most effective result. The chapter on the design process draws attention to the variety of knowledge and advice which the designer needs to draw upon to make materials choices with a high level of confidence.
