CALPHAD Gibbs Triangle Award

In celebration of the 150th birthday of Josiah Willard Gibbs, who was born in 1839, the Gibbs Triangle Award was established in 1989.  It will be awarded once every third to fifth year for outstanding contributions to studies of ternary and higher-order phase diagrams, their thermodynamic background and principles of construction as well as methods of calculation and assessment work.  The name of the award has been taken from Gibbs’ composition triangle, commonly used in representing ternary phase diagrams.  The recipient will be chosen by the associate editors of the CALPHAD journal together with prior recipients.  The award is in the form of a musical triangle.


List of recipients

1.  Larry Kaufman (1989, CALPHAD 13, 1989, 336), in recognition of his unique, pioneering contributions.  The fact that the thermodynamic CALculation of PHAse Diagrams is today accepted as an important scientific activity is largely due to his forsight and energy.  His introduction of the “lattice stability” concept has been instrumental in enabling thermodynamic assessments of phase diagrams to be extended to ternary and higher order systems, and he has been particularly active in assessing ternary metallic and ceramic systems of industrial importance.

2.  Taji Nishizawa (1994, CALPHAD 18, 1994, 368), in recognition of his contributions to the understanding of ternary phase diagrams, in particular the magnetic effects which he has studied by means of a unique combination of experimental and computational techniques.

3.  Arthur Pelton (1999)

4.  Mats Hillert (2000)

5.  Bo Sundman (2002)

6.  Gunnar Eriksson (2007), in recognition of his invaluable contribution to the study and calculation of phase diagrams and to computational thermodynamics through the development of internationally acclaimed software.

7.  Hans Leo Lukas (2008), in recognition of his outstanding seminal contribution to the development of thermodynamic software allowing to take into account various kinds of information improving the consistency of the Gibbs energy modeling, and for the development of thermodynamic descriptions for numerous binary, ternary and higher order systems.
