INTRODUCTION TO MECHANICAL METALLURGY BY GEORGE E Mechanical metallurgy is the area of metallurgy which is concerned. Metallurgy is a domain of materials science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds. Office Hours.

Particularly the chapters about Fatigue, Fracture and Stresses Calculations in my opinion are of such importance to design robust products.
The author is very didatic which makes the reading pleasant, of easy learning and application. A fantastic book if you are interested in metal material science. Very thorough and presented well. Excellent reference material for engineering students. Definitely would recommend.
Paperback Verified Purchase. An excellent primer on all aspects of mechanical metallurgy, covering the basics of dislocation theory for an understanding of mechanical properties of materials; fracture mechanics; and metal forming processes. Good Undergraduate metallurgy books are hard to find, this one's an essential for any forging class and any metallurgist's bookshelf. One person found this helpful.
Este es un excelente libro que incluye la teoria basica de mecanica asi como un resumen de la teoria de dislocaciones esto como una introduccion a los procesos de deformacion. Excelente libro I was very disappointed by the highlighter I purchased a more expensive book from the selection thinking it would be in better quality.
I was very disappointed by the highlighter in the book and you could see the previous owner's name. The book in general has a terrible index. The information inside is useful enough.

East Dane Designer Men's Fashion. Important assumptions in strength of materials are that the body which is being analyzed is continuous, homogeneous, and isotropic. A continuous body is one which does not contain voids or empty spaces of any kind. A body is homogeneous if it has identical properties at all points. A body is considered to be isotropic with respect to some property when that property does not vary with direction or orientation.
A property which varies with orientation with respect to some system of axes is said to be anisotropic.
While engineering materials such as steel, cast iron, and aluminum may appear to meet these conditions when viewed on a gross scale, it is readily apparent when they are viewed through a microscope that they are anything but homogeneous and isotropic. Most engineering metals are made up of more than one phase, with different mechanical properties, such that on a micro scale they are heterogeneous. Further, even a single-phase metal will usually exhibit chemical segregation, and therefore the properties will not be identical from point to point.
Metals are made up of an aggregate of crystal grains having different properties in different crystallographic directions. The reason why the equations of strength of materials describe the behavior of real metals is that, in gneral, the crystal grains are so small that, for a specimen of any macroscopic volume, the materials are statistically homogeneous and isotropic.
However, when metals are severely deformed in a particular direction, as in rolling or forging, the mechanical properties may be anisotropic on a macro scale.
Other examples of anisotropic properties are fiber-reinforced composite materials and single crystals. Lack of continuity may be present in porous castings or powder metallurgy parts and, on an atomic level, at defects such as vacancies and dislocations. It is further found that up to certain limiting loads a solid will recover its original dimensions when the load is removed.
The recovery of the original dimensions of a deformed body when the load is removed is known as elastic behavior.
The limiting load beyond which the material no longer behaves elastically is the elastic limit. If the elastic limit is exceeded, the body will experience a permanent set or deformation when the load is removed.
A body which is permanently deformed is said to have undergone plastic deformation. For most materials, as long as the load does not exceed the elastic limit, the deformation is proportional to the load.

This relationship is known as Hooke's law; it is more frequently stated as stress is proportional to strain. Hooke's law requires that the load-deformation relationship should be linear. However, it does not necessarily follow that all materials which behave elastically will have a linear stress-strain relationship.
Rubber is an example of a material with a nonlinear stress-strain relationship that still satisfies the definition of an elastic material. This is, however, primarily of academic importance. While part of the material covered in this chapter is a review of information generally covered in strength of materials, the subject is extended beyond this point to a consideration of stress and strain in three dimensions. The material included in this chapter is important for an understanding of most of the phenomenological aspects of mechanical metallurgy, and for this reason it should be given careful attention by those readers to whom it is unfamiliar.
In the space available for this subject it has not been possible to carry it to the point where extensive problem solving is possible. The material covered here should, however, provide a background for intelligent reading of the more mathematical literature in mechanical metallurgy. It should be recognized that the equations describing the state of stress or strain in a body are applicable to any solid continuum, whether it be an elastic or plastic solid or a viscous fluid.
Indeed, this body of knowledge is often called continuum mechanics. The equations relating stress and strain are called constitutive equations because they depend on the material behavior. In this chapter we shall only consider the constitutive equations for an elastic solid. It is the oldest of the metalworking arts, having its origin with the primitive blacksmith of Biblical times.
The development of machinery to replace the arm of the smith occurred early during the Industrial Revolution. Today there is a wide variety of forging machinery which is capable of making parts ranging in size from a bolt to a turbine rotor or an entire airplane wing.
Most forging operations are carried out hot, although certain metals may be cold-forged. Two major classes of equipment are used for forging operations. The forging hammer, or drop hammer, delivers rapid impact blows to the surface of the metal, while the forging press subjects the metal to a slow-speed compressive force.
The two broad categories of forging processes are open-die forging and closed-die forging.
Open-die forging is carried out between fiat dies or dies of very simple shape. The process is used mostly for large objects or when the number of parts produced is small.The stress distribution is arrived at by observing and measuring the strain distribution in the member, since stress cannot be physically measured.
