The Boundary Theory of Phase Diagrams and Its Application Rules forPhase Diagram Construction with Phase Regions and Their Boundariespresents a novel theory of phase diagrams. Thoroughly revised on the basisof the Chinese edition and rigorously reviewed, this book inspects thegeneral feature and structure of phase diagrams, and reveals that there existactually two categories of boundaries. This innovative boundary theoryhas solved many difficulties in understanding phase diagrams, and alsofinds its application in constructing multi-component phase diagrams orin calculating high-pressure phase diagrams. Researchers and engineers aswell as graduate students in the areas of chemistry, metallurgy and materialsscience will benefit from this book.Prof. Muyu Zhao was the recipient of the 1998 Prize for Progress in Scienceand Technology (for his work on the boundary theory of phase diagrams)awarded by the National Commission of Education, China, and many otherprizes.
