Grain Initiation and Grain Refinement: An Overview
Metals, 2022 Heterogeneous nucleation and grain initiation are two different processes in early-stage solidification (ESS), although both are deterministic. Heterogeneous nucleation refers to the formation of a 2-dimensional (2D) nucleus (a crystal plane of the solid)

Impeding Nucleation for More Significant Grain Refinement. [PDF]
Sci Rep, 2020 AbstractGrain refinement has been a topic of extensive research due to its scientific and technological importance as a common industrial practice for over seven decades. The traditional approach to grain refinement has been to reduce nucleation undercooling by the addition of potent nucleant particles.
