Handbook of materials selection
[...]... factor in materials selection is knowing how different classes of materials fail, which is the subject of the chapters that comprise the fifth part of the handbook The final aspect of materials selection involves knowing about the manufacturing processes used to make things from available classes of materials, which is the subject of the chapters that make up the sixth part of the handbook The handbook s... Invention is often born of the need, or just the desire, to improve something This simple statement (a restatement, in a way, of the old saw ‘‘necessity is the mother of invention’’) is the driving force behind the development of the Handbook of Materials Selection The audience for this handbook consists of practicing engineers and the people who work with them, all of whom need to determine what materials. ..

The powerful premise driving this 1,500-page handbook is that, in terms of materials selection, what works now, as well as what has failed in the past,... INITIAL SCREENING OF MATERIALS Fig 1 Stages of design and the related stages of materials selection 5 6 QUANTITATIVE METHODS OF MATERIALS SELECTION predictions based on simulated service tests or upon the most closely related mechanical, physical, or chemical properties For example, thermal shock resistance can be related to thermal expansion coefficient, thermal conductivity, modulus of elasticity, ductility,... relationships between the different selection parameters, often make the selection of a materials for a given component a difficult task If the selection process is carried out haphazardly, there will be the risk of overlooking a possible attractive alternative material This risk can be reduced by adopting a systematic material selection procedure A variety of quantitative selection procedures have been... questions as the ones I have posed above, I arranged the contents of the handbook in seven parts The first part, just one chapter long, but important nonetheless and a good introduction to the field of materials selection, is on quantitative methods that a practitioner can apply to materials selection problems The second part covers the range of major materials metallic, nonmetallic, and composite, from the... used for procuring materials Once you’ve obtained a material, what exactly do you have? The fourth part of the handbook deals with the issue of testing—what equipment is used to determine the properties of the different classes of materials, what standards govern test procedures, and what organizations are in the business of providing testing services What about the life expectancy of the thing you’ve
