Inthis case, entirely distinct constituents are seen in different parts ofthe metal. If the first class of alloys mentioned be compared to asolution of salt in water, the second may be represented by the caseof a solution of salt and water, which has been cooled to a pointwhere solid salt has been separated from the solution. This repre-sents by far the most common forms of alloys. In cooling, thehomogeneous molten mass separates out different constituents,which remain diffused through the still molten mother liquor, whichfinally freezes, forming the solid alloy. The properties of such analloy may be entirely different from those of the pure const
