Atomic Structure and Cohesion Between Atoms

Structure of the atom. It is accepted that an atom has an open structure. It consists of a relatively small central part, the nucleus, containing most of the mass; around the nucleus move at great speed one or m...

Chapter

Crystallography of Pure Metals

IN metallurgy, metallic elements are known usually as pure metals; the emphasis is on their elemental nature and the absence of intentional alloying, rather than on the specific degree of purity. However, many co...

Chapter

Binary Alloying

METALS are generally used in the form of alloys, unless some particular characteristic of pure metals is a paramount requirement, such as high electrical conductivity. An alloy is a combination of two or more ...

Chapter

Mechanical Working and other Sha** and Treating Processes

Mechanical working. Mechanical working performs two functions, namely, it shapes the metal, and refines the structure, giving general improvement in mechanical properties. The processes include those of rollin...

Chapter

Constitutional Diagrams of Binary Alloying

IT has been seen that a number of constituents may be formed in a complete alloy system. Further, alloys solidify in a variety of ways, giving rise to different configurations of the constituents. In addition,...

Chapter

Physical Examination of the Internal Structures of Metals

THE intention in this chapter is to give the student a brief yet broad idea of the various methods used for studying the micro- and crystal-structure of metals. It does not set out to give full practical instr...

Metal Melting, Alloying and Casting in Practice

Melting. Steel castings and ingots for working are generally cast directly from the refining furnace in which the steel is made. In certain cases there may be a separate melting and alloying stage. In the cast...

Effects of Stress on Metals

WHEN metals are stressed, they become deformed. The deformation may be wholly temporary, that is elastic; or, in addition, permanent deformation may result. The subject may be considered from two major aspects: (...
