Enthalpies of formation of binary transition hcp metal based alloys calculated by analytic embedded atom method model

A simple analytic modified embedded atom method (MEAM) including a modified term for hcp metals has been developed from the MEAM applied to the fcc and bcc metals. The enthalpies of formation of all binary alloy systems for eight transition hcp metals (scandium, yttrium, titanium, zirconium, halfnium, rhenium, ruthenium and cobalt) are calculated with the MEAM. The calculations are in agreement with the experimental data available and results calculated from the Miedema theory. One can conclude that our MEAM is also effective to apply to the hcp metals and their alloys.
