Abstract
Mg-Gd alloys is of great interest for many potential application especially in implant material. Higher mechanical properties is always the goal pursued by reserachers for the materials which generally have relatively still low strength, low ductile and loe hardness. From this aspect, the present paper reviews the recent report of a kind of Mg-Gd rolled which have been able to achieve strength compared with Mg-Gd casting alloys. The aim of this paper is to investigate the mechanical properties and microstructure forMg-Gd alloys that are rolled at high tempetaure with severe reduction. Mg-Gd rolled with 80% reduction will be applied by unidirectional and cross direction with purpose to find varian characteristic. The Temperature range are 400,450,500 and 550°C. The results of this experiment show that the highest hardness number obtained by single rolling specimen as 64.86 VHN at 550 °C. The highest ultimate tensile strength numbers obtained by cross rolling with 163.22 MPa at 550 °C. For the grain size, single rolling specimen has the smallest number with 46.33μm at 500 °C. Overall, temperature 500-550 °C give a big impact to improve Mg-1.6Gd alloys.
