Document Summary
Constitution of alloys and phase diagrams: define solid solution. A solid solution may be defined as a solid that consists of two or more elements automatically dispersed in a single-phase structure: differentiate substitutional and interstitial solid solutions. When the solute atoms substitute for parent solvent atoms in a crystal lattice, are called substitutional atoms, and the mixture of the two elements is called a substitutional solid solution: state gibbs"s phase rule. In interstitial solid solution , the solute atoms fit in to space between the solvent or parent atoms. Liquidus is the line or boundary that separates liquid and liquid + solid phase regions. Solidus is the line or boundary that separates solid and solid + liquid phase regions. Solvus is the line or boundary that separates single phase solid regions from two phase: what is liquidus line, what is solidus line, what is solvus line? solid regions, define triple point.
