《Table 1 Analyzed compositions of the Mg-Li-Ca alloys》
Mg-(3.5,6.5 wt%)Li-(0.2,0.5,1.0 wt%)Ca alloys were melted and cast by using commercial magnesium,pure Li,and pure Ca.The analyzed compositions are shown in Table 1.High purity Mg(99.95%)was used in a control group.Ingots of the alloys and pure Mg were extruded at280°C with a reduction ratio of 16 into bars.The samples were cut to a dish-shaped size(Ф10×2 mm)for microstructural characterization,corrosion measurements,cytotoxicity tests,and other in vitro tests,with the exception of tensile tests.Cylindrical rods(Ф0.7×5 mm)were machined parallel to the rolling direction for in vivo tests.All samples were mechanically polished to 2,000 grit,then ultrasonically cleaned in acetone,absolute ethanol and distilled water,before drying in open air.Polished specimens were etched in a 2%nitric acid alcohol solution and rinsed in distilled water.Afterwards,they were observed under an optical microscope(BX51M,Olympus,Japan).An X-ray diffractometer(XRD,Rigaku DMAX2400,Japan)was adopted to identify the phase compositions by using Cu Kαradiation at a scan rate of 4°min-1.
