CHARACTERIZATION OF MATERIALS
Abstract
The term, Characterization, as used in this report means essentially a description of those features of the composition and structure (including defects) of a material that are significant for a particular preparation, study of properties, or use, and suffice for reproduction of the material. Such work on characterization is, at present, fragmented as a field. While practically every laboratory using materials makes some specialized measurements which may partially define a material, rarely (if ever) do we get independently and thoroughly characterized materials. In a word, materials characterization, the cornerstone of materials science, is a neglected field. This committee, charged with making a detailed study of characterization in terms of composition, structure, defects, polycrystals, and polymers, has documented the state of the art in our ability to prepare a material, analyze it (composition, structure, and defects), and in turn to correlate these to property measurements. The study also assesses the situation surrounding some of the greatest needs for characterization; e.g., (a) better techniques and instruments, or more and better use of existing techniques and instruments, (b) better characterization for improved preparation of materials, or for improved study of materials, or for improved use of materials, and (c) more accurate and detailed characterization of materials in general, or just certain features of certain materials.
