Optimization of Mo Content in Beta-Type Ti-Mo Alloys for Obtaining Larger Changeable Young’s Modulus during Deformation for Use in Spinal Fixation Applications

Abstract:

In order to meet the requirements of the patients and surgeons simultaneously for spinal fixation applications, beta (β) -type Ti-Mo alloys with self-tunable Young’s modulus due to deformation have been developed to prevent the stress-shielding effect for patients and to suppress springback for surgeons. In this study, the effects of Mo on the deformation-induced omega-phase transformation were investigated and then the Mo content in binary Ti-Mo alloys was optimized in order to achieve a large increase in Young’s modulus via deformation-induced omega-phase transformation, leading to suppression of springback.
