Abstract: Computer simulation of tetrahedral lattice distortion of iron-carbon system was performed. Modern embedded atom potentials for $\mathrm{Fe}$-$\mathrm{C}$ system were used. It was shown that existing potentials can reproduce tetrahedral lattice distortion and don't allow to describe concentration dependence of martensite thermal stability.

Keywords: martensitic phase transition, molecular dynamic, embedded atom potential.
