Modeling of materials systems for long times commonly requires the use of separation of time scale methods. We discuss this general approach and present two example systems, a-Si3B3N7 and the generation of homogeneous sinters.
We present numerical investigations of the dynamics on the energy landscape of a realistic model of the high-temperature ceramic a-Si3B3N7. Below a critical temperature Tc = 2000 K, the system is no longer in equilibrium, and we predict that the material has a glass transition in this temperature range at high pressure. Analyzing the two-time energy correlation function shows aging in this system, which is linked to the geometrical properties of the energy landscape.
