Abstract

Dynamic Young's modulus of ß phase Ti-Nb binary alloys and Ti-Nb-Sn and Ti-Nb-O ternary alloys was measured at room temperature as a function of composition along with microstructural observations. Young's modulus of solution treated and quenched binary alloys exhibits a minimum value of 62 GPa for Ti-42wt.%Nb. Transmission electron microscopy indicates that athermal ω transformation is induced in unstable ß alloys, and the minimum in Young's modulus appears at a composition where athermal ω transformation is almost completely suppressed by quenching, as alloying content is increased. It is found that Sn and O additions suppress ω transformation and Young's modulus of solution treated and quenched alloys is decreased to 40-55 GPa by optimizing compositions in Ti-Nb-Sn and Ti-Nb-O alloys in consideration of the stability of ß phase. Composition dependence of Young's modulus can be estimated by the theoretical DV-Xa cluster method. Copyright
