TīmeklisThis sintering model is able to capture all the necessary mechanism to simulate simple solid-state sintering correctly. It was demonstrated by comparing it to 3D, in-situ images taken in a high-energy synchrotron during the sintering of Cu particles. The images below are from a simulation of the sintering process for a powder of Cu particles.
