Principles of Physical Metallurgy - Video course. COURSE OUTLINE. The aim of this course is to provide a basic understanding of the underlying principles that. Physical metallurgy principles, D Van Nostrand Company INC,. Princeton, New Jersey, . Lakhtin. Engineering physical metallurgy, CBS Publishers and . It introduces the fundamental principles of physical metallurgy and the design methodologies for alloys and processing. It discusses the.
On the other hand, the theoretical approach to physical metallurgy is premised on the belief that the properties of metals and alloys are determined by simple physical laws, and that it is not necessary to consider each alloy as a separate entity.
This book is intended for use as an introductory course of one or two semesters in physical metallurgy and is designed for all engineering students at the junior or senior level. A number of chapters dealing with advanced topics, such as Chapters 10, 11, 15, and 19 may be omitted in their entirety when the book is used for a one-semester course. Prerequisites are college physics, chemistry, and strength of materials.
An engineering course in thermodynamics or physical chemistry is also considered desirable but not essential. The approach is largely theoretical, but all major phases of metal behavior normally found in physical metallurgy textbooks are covered. In this respect, statistical mechanics and dislocation theory are used to explain plastic deformation and thermal effects in metals. Vacancies are treated in some detail because their study may be used to obtain a true appreciation for the meaning of activation energies in metals.
Deformation twinning is given considerable attention not only because this type of deformation has become increasingly more important, but also because twinning theory leads directly into the important subject area of martensite transformations. On the whole, it is believed that the treatment used in this book is in harmony with current trends toward a more fundamental approach in engineering education.
The author would like to acknowledge that the lectures of Dr. Nowick and Dr. Robertson at the Hammond Laboratory, Yale University, were largely instrumental in inspiring the writing of this book. The helpful suggestions from Dr. Rhines on the subject of creep are also gratefully acknowledged.
The major changes in the new edition are largely the xv xvi preface result of constructive suggestions and advice by Professor Richard W. One result of these suggestions is the inclusion of a chapter on nucleation and growth kinetics. The outline of this chapter was also inspired by a set of class notes kindly loaned to the author by Professor Heckel. The considerable assistance of Dr. John Kronsbein in revising and expanding Chapter 3, Elementary Theory of Metals, is also gratefully acknowledged.
Among the former subject areas are electron microscopy, fracture mechanics, superconductivity, superplasticity, dynamic recovery, dynamic strain aging, electrotransport, thermal migration, and emissary dislocations. The number of problems is substantially increased over that in the original book, in conformity with the current trend in engineering to place more emphasis on problem solving. Problems have been written with the aim of both illustrating points covered in the text and exposing the student to material and concepts not covered directly in the book.
The helpful assistance of Dr. John Hren, Dr. Robert T.
DeHoff, Dr. Derek Dove, Dr. Ellis Verink, and Dr. Rhines, all of the University of Florida, who either reviewed sections of the book or gave suggestions, is acknowledged with thanks. However, a number of significant improvements have been incorporated in the third edition. The International System of Units is now employed throughout text and problems. A chapter devoted to important nonferrous metal has been added.
Fracture mechanics is covered in much greater depth and breadth in a separate chapter. The treatment of solidification has been expanded and brought up to date and includes an extensive coverage of liquid metals as well as the Scheil equation and eutectic freezing. The section on the transmission electron microscope has been expanded and a detailed discussion of the scanning electron microscope has been added. Grain boundaries are now covered in a separate chapter that includes coincident site boundaries.
The subject of dislocations has been reorganized and consolidated. Chapter 4 considers the geometrical aspects of dislocations while Chapter 5 treats the relationship of dislocations to plastic deformation.
The phase diagrams in the text have been brought up to date. In the steel chapters, the transformations of austenite to peariite, bainite, and martensite, and the tempering of martensite have been modernized.
In the deformation twinning and martensite reactions chapter, less emphasis is placed on twinning phenomena per se while the role that twinning can play in the plastic deformation of polycrystalline metals has been added. In the martensite section, thermoelastic deformation and shape memory effects are now covered. Beshers of Columbia University for their extensive and constructive suggestions concerning material that needed to be corrected or added to the third edition. The authors would also like to acknowledge the assistance of Professors Paul C.
Holloway and Rolf N. Hummel, University of Florida. The condenser lenses are responsible for primary beam formation, while the objective lenses focus the beam that comes through the sample itself in STEM scanning mode, there are also objective lenses above the sample to make the incident electron beam convergent.
The projector lenses are used to expand the beam onto the phosphor screen or other imaging device, such as film. The magnification of the TEM is due to the ratio of the distances between the specimen and the objective lens' image plane. It is noted that TEM optical configurations differ significantly with implementation, with manufacturers using custom lens configurations, such as in spherical aberration corrected instruments,  or TEMs using energy filtering to correct electron chromatic aberration.
Components[ edit ] The electron source of the TEM is at the top, where the lensing system 4,7 and 8 focuses the beam on the specimen and then projects it onto the viewing screen The beam control is on the right 13 and 14 A TEM is composed of several components, which include a vacuum system in which the electrons travel, an electron emission source for generation of the electron stream, a series of electromagnetic lenses, as well as electrostatic plates.
The latter two allow the operator to guide and manipulate the beam as required.
Also required is a device to allow the insertion into, motion within, and removal of specimens from the beam path. Imaging devices are subsequently used to create an image from the electrons that exit the system.
TEM components such as specimen holders and film cartridges must be routinely inserted or replaced requiring a system with the ability to re-evacuate on a regular basis. As such, TEMs are equipped with multiple pumping systems and airlocks and are not permanently vacuum sealed. The vacuum system for evacuating a TEM to an operating pressure level consists of several stages.
Initially, a low or roughing vacuum is achieved with either a rotary vane pump or diaphragm pumps setting a sufficiently low pressure to allow the operation of a turbo-molecular or diffusion pump establishing high vacuum level necessary for operations.
To allow for the low vacuum pump to not require continuous operation, while continually operating the turbo-molecular pumps, the vacuum side of a low-pressure pump may be connected to chambers which accommodate the exhaust gases from the turbo-molecular pump.
For these very low pressures, either an ion pump or a getter material is used. Poor vacuum in a TEM can cause several problems ranging from the deposition of gas inside the TEM onto the specimen while viewed in a process known as electron beam induced deposition to more severe cathode damages caused by electrical discharge. The specimen holders hold a standard size of sample grid or self-supporting specimen. Standard TEM grid sizes are 3. The sample is placed onto the meshed area having a diameter of approximately 2.
Usual grid materials are copper, molybdenum, gold or platinum. This grid is placed into the sample holder, which is paired with the specimen stage. A wide variety of designs of stages and holders exist, depending upon the type of experiment being performed. In addition to 3. These grids were particularly used in the mineral sciences where a large degree of tilt can be required and where specimen material may be extremely rare.
Once inserted into a TEM, the sample has to be manipulated to locate the region of interest to the beam, such as in single grain diffraction, in a specific orientation. To accommodate this, the TEM stage allows movement of the sample in the XY plane, Z height adjustment, and commonly a single tilt direction parallel to the axis of side entry bolders. The first part of the book discusses the structure and change of structure through phase transformations.
The latter part of the books deals with plastic deformation, strengthening mechanisms, and mechanical properties as they relate to structure. The book also includes a chapter on physical metallurgy of steels and concludes by discussing the computational tools, involving computational thermodynamics and kinetics, to perform alloy and process design.

The phenomena are described in a conceptional and demonstrative manner; a link to real materials application is elaborated for many possible applications.
It is especially worth mentioning that the consequent numerical description of the fundamental design principles of metals offers the entrance for physics-based modelling of materials and processes.
It covers the well-known topics of phase transformations under equilibrium and non-equilibrium conditions, as well as the strengthening mechanism and the way it can be used during metal production or treatment. The last chapter on Alloy Design is a nice integration of the concepts explained and takes the book from the level of explaining what is known already to the level of the start of a toolbox to redesign new alloys based on conceptual thinking.
Gregory N. His research is concerned with processing-structure-properties in metallic materials, dealing with transformation kinetics in TRIP steels, corrosion-induced hydrogen trapping in aluminum alloys and rolling contact fatigue in rails.
