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)

Effect of solutes on grain refinement
Progress 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 ...

New grain refinement method for aluminum cast alloys without adding grain refiner.
Journal of Advanced Science, 2001 Grain refiner has conventionally been added during the casting process of grain refinement, but it has recently become a recycling problem, which calls for the efforts for development of a new grain refinement method. In this paper, a technological breakthrough has been achieved, where grain refinement was successfully completed by applying ultrasonic ...
