Abstract

It is well known that local strains are introduced into the crystal lattice due to the size mismatch between alloying element M and mother metal X. However, to the author’s limited knowledge, there are few investigations of such local lattice strains in metals. In this chapter, presented is a series of calculated results on the local lattice strains around alloying elements M in mother metals X of Mg, Ti, and Fe. Local strains are calculated by optimizing the positions of X atoms neighboring an isolated M atom in the supercell using the pseudopotential method.
