We study the idea that far-from-equilibrium states can be modeled with an equilibrium-like statistical mechanics description. We show, using molecular dynamics simulations, that an effective temperature, which controls a Boltzmann-like distribution of the local structures, can be used as a state variable for the non-equilibrium process of radiation amorphization. We demonstrate a predictive theory for the effective temperature and show how it can be used to describe the transient and steady-state structure of the material.
