Theory and Optimization of Sintering Processes

摘要

The goals of our research are the understanding of the time- and temperature-dependent evolution of clusters, cluster fusion, grain boundary transport and motion, and ultimately the development of a comprehensive, microscopic theory of sintering processes. In order to achieve these goals several scientific advances are necessary. A number of them require multidisciplinary efforts and benefit substantially from the diverse yet complimentary backgrounds of the principal investigators. In order to be able to study theoretically the time evolution of cluster structures one has to develop fast and reliable methods for calculating total energies of fairly large clusters as well as forces on all the atoms.
