Abstract
A constitutive model of powder densification during spark plasma sintering was adapted to introduce the contribution of particle rearrangement. Such contribution was quantified by a particle-packing factor describing changes in packing states upon compaction of spherical and non-spherical powder particles. To validate this addition, atomized and cryomilled aluminum-magnesium powders were sintered using single-step and two-step sintering schedules. Densification simulations of each powder and sintering schedule agreed well with experimental results, supporting the proposed description of the particle rearrangement contribution.
