A classical interatomic potential is trained within the GAP framework with the goal of reproducing both plastic properties and phase transition for iron. We first build a reference compact database based on tight-binding calculations of the ferromagnetic bcc and antiferromagnetic hcp phase, as well as the transition path between the two structures. We then show how the GAP formalism enables the reproduction of diverse properties that include equation of state, elasticity, plasticity, and phase transition for this complex system.
