- Development of Beta Titanium Alloys with Low Young's Modulus

Development of beta Ti alloys with low Young's modulus (modulus of
elasticity) is strongly demanded in various fields. Young's modulus of
typical Ti-V, Ti-Mo and Ti-Nb binary alloys with similar phase
diagrams was measured as a function of composition along with
microstructural observations. Young's modulus fo beta Ti binary alloys
solution treated and quenched exhibits minimum value of 72 GPa for Ti-
26%V, 85 GPa for Ti-15%Mo, and 62 GPa for Ti-42%Nb. Transmissioin
electron microscopy indicates that athermal omega transformation is
induced in unstable beta alloys, and the minimum in Young's modulus
appears at a composition where athermal omega transformation is
suppressed by increasing alloying content. Based on the obtained
results on the binary alloys, ternary Sn additions were investigated
to lower Young's modulus by suppressing omega transformation. It is
found that the optimization of composition in Ti-Nb-Sn alloys
decreases Young's modulus to about 50 GPa under a soution treated
