TL;DR
This study uses a numerical model to analyze the sintering behavior of close packed spheres in BCC, FCC, and HCP arrangements, revealing ideal sintering with no grain growth until full density and shape changes to tetrakaidecahedron.
Contribution
It provides a detailed numerical analysis of sintering in close packed sphere systems, highlighting shape evolution and grain growth behavior.
Findings
No grain growth until full density
Spherical grains transform into tetrakaidecahedron
Sintering behavior is ideal in all systems
Abstract
The sintering behavior of close packed spheres is investigated using a numerical model. The investigated systems are the body centered cubic (BCC), face centered cubic (FCC) and hexagonal closed packed spheres (HCP). The sintering behavior is found to be ideal with no grain growth until full density is reached for all systems. During sintering the grains change shape from spherical to tetrakaidecahedron, similar to the geometry analyzed by Coble (R. L. Coble, J. Appl. Phys. 32 (1961) 787).
