"system":a specific body of material under consideration.Or it may relate to the series of possible alloys consisting of the same compounds,but without regard to alloy composition. "Solvent"represents the element or compound that in the greatest amount(host atoms,host material). "Solute"is used to denote an element or compound present in a minor concentration.
