John Werner Cahn

U.S.A. / January 9, 1928
Materials Scientist
Emeritus Senior NIST Fellow, National Institute of Standards and Technology
Affiliate Professor, University of Washington

"Outstanding Contribution to Alloy Materials Engineering by the Establishment of Spinodal Decomposition Theory"
Dr. John W. Cahn developed the theory of spinodal decomposition in alloy materials by incorporating the strain energy term into the free energy of the alloy system. It has made it possible to predict the optimal microstructures of alloy materials and to maximize their functions. The theory has led to the establishment of a design guideline for the development of alloy materials and contributed to the progress of both materials science and materials industry.
