The Biocompatibility of Degradable Magnesium …

Magnesium and magnesium alloys are of special interest as structural materials since their high specific strength enables them to be applied as implants. In particular the related elastic modulus of magnesium (41–45 GPa), compared to natural bone (3–20 GPa), makes this metal an ideal bone substitute or osteosynthesis material by decreasing the “stress-shielding” effect [ 2 ].

Study of second phase in bioabsorbable magnesium …

Thermodynamical stabilities of four conventional second phases as well as magnesium matrix in bioabsorbable magnesium alloys were investigated theoretically via computer calculation method. Model of individual phase and systems including phase and four water molecular (phase-4H 2 O) were established to simulate the in vitro and in vivo environment.
