Grain Initiation and Grain Refinement: An Overview [PDF]

open access: yesMetals, 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)

Effect of solutes on grain refinement

open access: yesProgress in Materials Science, 2022
Abstract Grain refinement not only enhances the mechanical performance of as-cast metallic materials but also provides an effective mechanism for controlling cast defects, such as macro-segregation, porosity and coarse second phase particles. Therefore, understanding grain refinement of alloys with different solute additions is of both theoretical ...
