Professor Jan Vřešťál and His Contributions Towards the Implementing of Ab Initio Data into the CALPHAD Method and Extension of the Phase Diagram Calculations Down to 0 K

The paper describes the development of implementation of ab initio results into the CALPHAD method and of calculations of phase diagrams down to 0 K, where Prof. Jan Vřesťal is among pioneers paving new ways. His scientific activities contributed considerably to improved versatility and effectivity of the CALPHAD method, which was supported by numerous descriptions of binary and ternary systems accomplished with the help of data having stronger physical grounds and thus bringing more physics into the CALPHAD approach. He also brought the CALPHAD method to Czechoslovak scientific institutions and, due to his merit, numerous younger colleagues learned to apply this very effective approach.
