Kinetics of Crystallization and Gelation in Colloidal Suspensions
… arising from three underlying processes at the particle level, viz., aggregation, dissociation, and rearrangement. Particles aggregate via Brownian encounters into clusters that have open structures. Subsequently, these particles rearrange into crystalline configurations to minimize their free …

Production of a nanostructured copper by Spark Plasma Sintering
… DSC investigation. The influence of temperature, particle size, pressure on the densification and sintering mechanisms as well as that of heating rate and holding time on the structural evolution has been investigated. Particle rearrangement, local deformation, bulk deformation and sintering are …

Multiscale modeling in granular flow
… stems from the discreteness of the constituent particles, and a key theme of this work has been the connection of the microscopic particle motion to a bulk continuum description. This led to development of the "spot model", which provides a microscopic mechanism for particle rearrangement in …

Low-Temperature Densification of Lead Zirconate Titanate With Vanadium Pentoxide Additions
… defect concentration, primarily in regions of particle-particle contacts. Rapid densification, by almost immediate particle rearrangement and pore removal, occurs with melting of the lead vanadate phase due to the large cohesive forces generated. The rate of densification is further increased …

Effects of powder conditioning on the quality, microstructure and mechanical properties of sintered titanium alloys
… powder could be separated into two stages: a particle rearrangement (PR) stage, which occurred in a compacting pressure range of 0-200MPa, followed by a plastic deformation (PD) initiated (PR) stage from 200-1000MPa. The existence of stage II was due to the low plastic deformability of …

Classification and Densification of Municipal Solid Waste for Biofuels Applications
… that the primary mechanism of densification was particle rearrangement. Application of the Peleg and Moreyra model for analysis of relaxation properties of the compressed materials determined the asymptotic modulus of the residual stress to be between 89 and 117 MPa for all experimental …
