THEORY OF DISLOCATION IN METALS AND ITS APPLICATION

Abstract

THEORY OF DISLOCATION: Types of imperfections in the crystal lattice, Types (structure) of dislocations, Movement of dislocations, Stress field and dislocation energy, Forces acting on the dislocations, Formation of dislocations, Intersection of dislocations, Dislocation reactions,AND Actual resistance to dislocation movement. EXAMPLES OF THE APPLICATION OF THE THEORY OF DISLOCATION: Elastic limit, Yield-point elongation and peak, Mechanical aging, Blue brittleness in steel, Hardening and the stress-strain diagram, Internal friction, Metal fatigue, Creep in metals, Long-term strength of metals, New principles in improving strength, The role of dislocations in phase transformations and structural changes, Brittle failure, and Methods of viewing dislocations and determining the dislocation density.
