The increased utilization of the electron microscope in the study of metals brought on by the introduction of the double condenser lens microscope in 1954 has resulted in the development of many new techniques for the preparation of specimens for direct transmission microscopy to augment the older indirect surface replication techniques. This book, designed as a laboratory handbook, presents the general principles of replication techniques and methods for thin-film preparation with excellent clarity in the beginning chapters. The balance of the book goes into detail on the selection of methods to be used for particular investigations and the specifics of specimen preparation techniques for many of the pure metals and alloys that one is apt to encounter in the metallurgical laboratory. The techniques are presented in tabular form, listed alphabetically by metals. An appendix of useful information includes many references, a listing of suppliers of materials and equipment, and tables of basic electron diffraction and crystallographic data. The book is devoid of theoretical discussions of the principles of either the electron microscope or the various specimen preparation techniques. Its value, to professionals and technicians alike, lies in its clear presentation of practical laboratory methodology. EMIL
