At this level, on the order of 1022 to 1023 impu- rity atoms will be present in one cubic meter of material. Solid Solutions A solid solution forms when, as the solute atoms are added to the host material, the crystal structure is maintained and no new structures are formed. The present discussion is concerned with the notion of a solid solution; treatment of the formation of a new phase is deferred to Chapter 9. A solution is composed in majority of a solvent there is more of it then the solute.
Common example of a solution in every day life is salt or sugar solute dissolved in water solvent. For the substitutional type, solute or impurity atoms replace or substitute for the host atoms Figure 4. Appreciable quantities of a solute may be accommodated in this type of solid solution only when the difference in atomic radii be- tween the two atom types is less than about Otherwise the solute atoms will create substantial lattice distortions and a new phase will form.
In normal ambient envi- ronments, pure silver is highly corrosion resistant, but also very soft.
This kind of defect is also represented in Figure 4. In metals, a self-interstitial intro- duces relatively large distortions in the surrounding lattice because the atom is sub- stantially larger than the interstitial position in which it is situated. For metallic materials that have relatively high atomic packing factors, these interstitial positions are relatively small.

Main characteristics of a solution Solution is homogenous That the solution is a homogenous mixture means that it forms a single phase. Atomic size factor.
Alloying with copper significantly enhances the mechanical strength without depreciating the cor- rosion resistance appreciably. A solution is stable in given conditions. The substance in which the solute is dissolved is called a solvent. Jump to navigation. As ensuing discussions indicate, a number of other material parameters have an exponential dependence on temperature similar to that of Equation 4.
Crystal structure. Several features of the solute and solvent atoms determine the degree to which the former dissolves in the lat- ter, as follows: Usually it is easy do determine which substance is a solute and which is a solvent.
If two liquids, soluble in each other such as water and alcohol are combined, a liquid solution is produced as the mol- ecules intermix, and its composition is homogeneous throughout.
That the whole solution is on one phase means that the wole of it is either gasous, liqiud or solid. Solution is in one phase That the whole solution is on one phase means that the wole of it is either gasous, liqiud or solid.
A sugar dissolved in water seems to take on it's characteristics and there is more water than sugar in the solution.
