Historic Note No. 2: CALPHAD Assessments

Historic Notes is a series of articles that explore the history of materials science, thermodynamics and other related fields through the scientists who made the discoveries.

This article was generously written by Prof. Mats Hillert from the Royal Institute of Technology (Stockholm). Thermo-Calc Software would like to thank Prof. Hillert for this contribution to our blog.

CALPHAD Assessments

In 1908, seven years after Bakhuis Roozeboom’s treatise “Die Heterogenen Gleichgewichte”, which brought attention to the connection between phase diagrams and thermodynamics, another Dutch scientist, van Laar, showed how the shape of typical T,x phased diagrams can be predicted from expressions representing the Gibbs energy of the individual phases as functions of T and composition, x.

Lattice Stabilities

Larry KaufmanThe CALPHAD technique, most likely started by Johansson in 1937, but abandoned shortly thereafter, was finally taken up at MIT in the early 1950s. Professor Morris Cohen, who studied martensite, had a graduate student, Paranjpe, who had some interest in thermodynamics. He found and appreciated Johansson’s paper, published in German and containing the word “Martensit” in the title. He showed the paper to his professor, who soon engaged a new graduate student, Larry Kaufman, to study the formation of martensite in the Fe-Ni system and to relate it to the results of what we now regard as a CALPHAD assessment.
