In vitro of Mg-1.6 Gd alloys after hot extruded for biomaterial application

Mg-1.6Gd (wt%) alloys have attracted interest in biodegradable implant materials because of the potential to eliminate secondary surgeries. The purpose of this study was to evaluate the in vitro degradation performance of the alloys after the thermo-mechanical process (hot extruded and hot rolled) and to determine whether the materials are sustainable for further investigation. The performances of the Mg-1.6Gd alloys was using cell viability (MTT) test during the experiment. The results showed that verified viable the osteoblast cell on all the different thermo-mechanical process and no obvious toxic effect within the various time.
