英文摘要
The additional alloying elements affected the fracture toughness and the fracture mechanism in the fine-grained magnesium alloys, and these behaviors were closely related to the segregation energy. The alloys that had low segregation energy indicated high fracture toughness and the ductile fracture, while the alloys with large segregation energy exhibited low fracture toughness and the intergranular fracture. The change in the lattice parameter ratio was found to be the influential material parameter regardless of whether the grain boundary embrittlement was for enhancement or suppression in magnesium.
