Sintering Mechanism of Nanoscale Tungsten Powder

Atomistic simulations focusing on sintering of crystalline tungsten powders at the submicroscopic level are played to shed light on the processing of the nanoscale powders. When the sintering simulations performed, the neck growth and shrinkage were calculated at the same time. That lead to the possibility of extend these results to the global physical property evolution through sintering. With variations in temperature, pressure, particle configuration, additives, and crystalline misalignment between particles during sintering, the densification and grain growth were calculated. The findings were of great importance for a virtual method to creating the processing and materials design to nanoscale powders. Maybe in near future, there will be a better sintering mechanism of nanoscale tungsten powder comes out.
