    : Intermetallic-Based Alloys for Structural and Functional Applications: Volume (MRS Proceedings) (): Martin Palm, Bernard P. Bewlay, K. Sharvan Kumar, Kyosuke Yoshimi: Books. Alloys can be classified as solution alloys, heterogeneous alloys, and intermetallic compounds. Solution alloys are homogeneous mixtures in which the components are dispersed randomly and uniformly. Atoms of the solute can take positions normally occupied by a solvent atom, thereby forming a substitutional alloy, or they can occupy interstitial.

    substitutional alloys. Elements that can form substitutional alloys have atoms with atomic radii that differ by no more than about 15%. Because there are slight differences in size and electronic structure, the less abundant atoms in substitutional alloy distort the shape of the lattice of the moreFile Size: KB. @article{osti_, title = {A Bragg-Williams model for the thermodynamic activity and the thermodynamic factor in diffusion for ordered alloys with substitutional defects}, author = {Ikeda, T and Numakura, H and Koiwa, M}, abstractNote = {A pair interaction model for describing the thermodynamic activities in binary ordered alloys with substitutional defects (antisite atoms) has been.

Ezhov, D. Davydov, N. Vinogradova, P. Terent’ev. We have studied the effect of atom arrangements in the ground state structures of substitutional ordered alloys on their mechanical properties using nickel–molybdenum-based alloys as model.

In contrast to substitutional alloys, a strong site preference is characteristic for many intermetallic compounds. Caused by the chemical bonding [ 13 – 15 ], the site preference can provide the stability, which is needed to exclude segregation and thus to maintain the crystal and electronic structure of the intermetallic compound under Cited by:   Best Answer: a) Substitutional Alloy, because atoms of the solute in a Solid solution occupy the positions normally occupied by solvent atoms.

b) Intermetallic Compound, because They are compounds rather than mixtures. c) Interstitial Alloy, because The solute atoms occupy interstitial positions in the "holes" between solvent atoms.
