Description

Modern Metallography focuses on the defects in the properties of metals, such as precipitates, cracks, grain boundaries, dislocations, stacking faults, and impurity atoms. The publication first offers information on reflected light microscopy and high temperature microscopy. Discussions focus on specimen preparation, defects of lenses, methods of increasing the resolving power of an objective, long working distance objectives, and typical hot-stage experiments. The text then elaborates on surface topography and polarizing microscope, including oblique illumination, interferometry, examination of anisotropic surfaces, and other uses of polarized light microscopy. The text takes a look at X-ray metallography and specialized X-ray diffraction techniques. Topics include Laue method and orientation, structure factor, powder method and the accurate measurement of lattice parameters, Bragg law, sheet textures, and preferred orientation. The publication further elaborates on electron microscopy and metallography at the atomic level. The manuscript is a valuable reference for students and readers interested in modern metallography.

About the Authors

R. E. Smallman

After gaining his PhD in 1953, Professor Smallman spent five years at the Atomic Energy Research

Establishment at Harwell before returning to the University of Birmingham, where he became Professor

of Physical Metallurgy in 1964 and Feeney Professor and Head of the Department of Physical

Metallurgy and Science of Materials in 1969. He subsequently became Head of the amalgamated

Department of Metallurgy and Materials (1981), Dean of the Faculty of Science and Engineering, and

the first Dean of the newly created Engineering Faculty in 1985. For five years he wasVice-Principal

of the University (1987-92).

He has held visiting professorship appointments at the University of Stanford, Berkeley, Pennsylvania

(USA), New SouthWales (Australia), Hong Kong and Cape Town, and has received Honorary

Doctorates from the University of Novi Sad (Yugoslavia), University ofWales and Cranfield University.

His research work has been recognized by the award of the Sir George Beilby Gold Medal of the

Royal Institute of Chemistry and Institute of Metals (1969), the Rosenhain Medal of the Institute of

Metals for contributions to Physical Metallurgy (1972), the Platinum Medal, the premier medal of

the Institute of Materials (1989), and the Acta Materialia Gold Medal (2004).

Hewas elected a Fellowof the Royal Society (1986), a Fellowof the RoyalAcademy of Engineering

(1990), a Foreign Associate of the United States National Academy of Engineering (2005), and

appointed a Commander of the British Empire (CBE) in 1992. A former Council Member of the

Science and Engineering Research Council, he has been Vice-President of the Institute of Materials

and President of the Federated European Materials Societies. Since retirement he has been academic

consultant for a number of institutions both in the UK and overseas.
