As bioabsorbable materials, magnesium alloys are expected to be totally degraded in the body and their biocorrosion products not deleterious to the surrounding tissues. It's critical that the alloying elements are carefully selected in consideration of their cytotoxicity and hemocompatibility. In the present study, nine alloying elements Al, Ag, In, Mn, Si, Sn, Y, Zn and Zr were added into magn...

Application prospects in automotive industry have led to extensive studies on 6xxx alloys in recent years. These alloys often contain Cu in varying amounts. This leads to the formation of the quaternary Al–Mg–Si–Cu family of alloys that may exist either as a 6xxx or a 2xxx alloy. These alloys have distinctive properties in part due to the occurrence of a phase, designated as Q, which is stable ...

In this study, the corrosion behavior of Mg-Zn-Se and Mg-Zn-Cu alloys was investigated to evaluate their corrosion behavior related to use as implantable biomaterials. The corrosion behavior of these alloys and a commercially available Mg-Zn alloy were examined using static solution electrochemical testing, dynamic solution gravimetric testing, ion leaching testing, and microscopic evaluation. ...

While lean Mg–Zn–Ca alloys are promising materials for temporary implants, questions remain on the impact of Zn and Ca microstructure. In this context, precipitation in Mg-1.5Zn-0.25Ca (in wt.%), initially extruded at 330°C, towards Mg–Ca binary precipitates or Ca–Mg–Zn ternary was probed a multiscale correlative approach using atom probe tomography (APT) analytical transmission electron micros...
