The properties of hot rolled binary magnesium calcium alloy for use as a biodegradable material within bone

Binary Mg-Ca alloys with various Ca contents were fabricated under controlled condition. X-ray diffraction (XRD) analysis and optical microscopy observations showed that Mg-Ca (x= 1-5 wt %) alloys were composed of two phases, a (Mg) and MgzCa. The results of hardness test and in vitro corrosion test...
