Designing grain refinement passes for multi-direction forging: A phase-field crystal study
Journal of Materials Research and Technology, 2023 Multi-directional forging is an effective plastic deformation method for polycrystalline grain refinement, and the degree of refinement is closely related to the number of forging passes. However, the relationship between the degree of refinement and the
