EQUILIBRIUM AND THERMODYNAMIC PROPERTIES OF GREY, WHITE, AND LIQUID-TIN

The thermodynamic properties of various phases of tin are calculated e mploying the method of adiabatic switching with modified embedded atom method (MEAM) potentials. The experimental alpha --> beta and beta -- > liquid transition temperatures are reproduced within an 11% accuracy . Good agreement with experiments is also obtained for other thermodyn amic quantities. We demonstrate the versatility and accuracy of MEAM b y how well it reproduces both metallic and covalent phases of tin over a wide temperature range and over a wide ranee of densities.
