主　　题：Bi-direction drawing Texture Mechanical property Corrosion resistance 

摘      要：Mg-Zn-Nd alloy is a promising biodegradable metal material for surgical staples during the reconstruction of digestive tract due to its good biocompatibility and suitable mechanical ***,its deformation property and corrosion resistance should be improved to make better safety and effectiveness of *** the present study,bi-direction drawing was adopted to maintain the initial texture characteristics,and improve mechanical property and corrosion resistance of Mg-2Zn-0.5Nd *** results showed that the microstructure after bi-direction did not change too much,but the texture could maintain its initial *** ductility of the alloy with 60%accumulative area reduction after bi-direction drawing was increased by 70%,indicating that an outstanding deformation property of Mg-Zn-Nd alloy can be obtained by bi-direction *** corrosion resistance was also improved after bi-direction drawing compared with that under single direction drawing.
