Outline of Final Research Achievements

The purpose of this study was to achieve both high strength and high damping capacity through thermomechanical processing in biodegradable magnesium, which is applicable to orthopedic implants. To begin with, the effect of microstructural factors including grain size, texture and the existence of twins on damping capacity was clarified in pure magnesium. By controlling the microstructure of Mg-Ca alloys through thermomechanical processing, the alloy showed higher strength and damping capacity.
