Moitra, A., Kim, S., Kim, S., Park, S. J., German, R., & Horstemeyer, M. (2010). Investigation on Sintering Mechanism of Nanoscale Tungsten Powder Based on Atomistic Simulation. AIP Conference Proceedings. Pohang, Korea. 1252, 1176.

Atomistic simulations focusing on sintering of crystalline tungsten powders at the submicroscopic level are performed to shed light on the processing on the nanoscale powders. The neck growth and shrinkage were calculated during these sintering simulations, so it is possible to extend these results to the global physical property evolution via sintering. The densification and grain growth during sintering were calculated with variations in temperature, pressure, particle configuration, additives, and crystalline misalignment between particles. These findings lay a foundation for a virtual approach to setting the processing cycles and materials design applicable to nanoscale powders.
