CALCULATIONS OF THE THERMODYNAMIC PROPERTIES FOR BINARY HCP ALLOYS WITH SIMPLE EMBEDDED-ATOM METHOD MODEL

The simple embedded atom method model for hcp metals developed by John son has been applied to calculate the thermodynamic properties of all binary alloy systems for the eleven transition hcp metals. It has been shown that the agreement with the calculation results from Miedema th ermodynamic theory and with the available experimental data is general good, but the agreement with the experimental data for the formation energy of Co-Y alloys is weak, which implies that a more better model for hcp metals is needed.
