Introduction,lic materials (metals and their mixtures) play an indispensable role in engineering, technology, and industry. All tools and machines ranging from a sewing needle to automobiles and aircraft are made of various metallic materials. These materials thus constitute one of the most important classes of

Physical Effects of Impurities in Metals,ence of an impurity due to its different electronic structure, produces disturbance in the conduction electron distribution, distortion of the crystal lattice, and polarization of electronic charge. These facts change the various electronic properties of metallic solids significantly. Theoretical un

Elasticity Theory of Point Defects,st metal. The impurity-induced strain field extends to a number of NNs around an impurity and hence gives rise to an internal stress in the crystal lattice. A theoretical estimation of the stress and strain field on each atom is difficult as we do not have an exact knowledge of the forces responsibl

Conduction Electron Distribution in Metallic Alloys,Δ..(.) is screened by the conduction electrons of the host metal thus causing redistribution of the conduction electrons. The change in conduction electron density Δ.(.) produces an additional change in the impurity potential giving rise to a net excess impurity potential Δ.(.), usually called .. Th
