Abstract

The study shows that the microstructural difference between the fine-grained die-cast and coarse-grained sand-cast magnesium-based alloys has no significant effect on the in-vitro degradation behaviour. However, the post-degradation analysis of the alloys suggest that the high volume fraction of secondary phase particles in the die-cast alloy may not be suitable for biodegradable implant applications, primarily due to the high stability of the secondary phase particles in physiological conditions.
