| Abstract Scope |
The sintering of powder compacts of spherical particles with different packing and particle size distributions are simulated using a three dimensional kinetic Monte Carlo (kMC) model. The sintering of mono-sized spherical particles packed in BCC, FCC, HCP is compared to randomly packed mono-sized particles. The regularly packed powder compacts showed ideal sintering behavior by densifing to full density without grain growth. The sintering of powder randomly packed mono-sized was near-ideal with little grain growth until densities > 90%. The sintering behavior of compacts with normal and log-normal size distributions were also characterized as a function of the width of their size distributions. Densification rate and final density were inversely proportional to the initial widths of the distributions. The microstructural evolution of these powder compacts will be presented in detail.We thank The Danish Agency for Science, Technology and Innovation, Project 09-072888.
