Magnesium is a suitable candidate material for temporary implant applications, such as a miniplate, due to its biocompatibility, density, and elastic modulus comparable to that of human bone. The biodegradability property of magnesium can minimize the need for a second surgery after the healing process, thereby reducing costs and pain for patients. On the other hand, microforming is a promising technology for manufacturing miniplates with high production rates and good mechanical properties. However, the application of magnesium in microforming is limited and remains a challenge in resolving issues related to the size effect in microforming and the low formability of magnesium, especially at room temperature. Grain refinement and homogenization are alternative approaches to controlling the size effect in magnesium microforming and improving formability. As the grain refinement process influences the mechanical and corrosion behavior of magnesium, this research shows that the grain refinement process for pure magnesium improves the overall performance of the microforming process for implant applications.
