N2 - This research focused on development of new titanium alloys with changeable Young's modulus for spinal fixation applications by taking advantage of deformation-induced phase transformation. The microstructures, Young's moduli, and tensile properties of metastable Ti-30Zr-x(Cr, Mo) alloys subjected to solution treatment (ST) and cold rolling (CR) were investigated. During cold rolling, deformation-induced phase transformation occurs in all these alloys. The change in Young's modulus after cold rolling is highly dependent on the type of deformation-induced phase. The decrease in Young's modulus after cold rolling is attributed to the deformation-induced α′ phase, while the increase in Young's modulus after cold rolling is attributed to the deformation-induced to phase in {332} mechanical twinning. Ti-30Zr-3Cr-3Mo alloy exhibiting excellent tensile properties and a changeable Young's modulus is a promising candidate for spinal fixation applications.
