Microstructure and mechanical properties of cold-rolled TiNbTaZr biomedical titanium alloy
Materials Science and Engineering A 490 (2008) 421-426，-0001，（）：
This work investigates the cold workability of TiNbTaZr biomedical titanium alloys. During cold rolling, the alloy exhibits excellent workability. Dislocations slipping, stress-induced martensite phase transformation and deformation twins appear during the deformation. With the increase of the reduction of cold deformation, dislocations slipping contributes much to the plastic deformation. The mechanical properties with higher strength, better elongation and lower elastic modulus are obtained at the reduction of 99%. Grains refinement is also obtained during the deformation of dislocations slipping.
