Abstract
The addition of 3%∼9% Zr on the martensitic transformation of Ti-18Nb(at.%) alloy was investigated. The results of microstructure and X-ray diffraction (XRD) analysis show that the phase constitution of as-quenched Ti-18Nb-9Zr(at.%) alloy consists of the retained β matrix and α″ martensite, while that of the other three alloys is single α″ martensite. No trace of athermal ω phase was found in any of the as-quenched alloys. Unlike the effect of Nb addition on the martensitic transformation start temperature M s of Ti-18Nb(at.%) alloy, M s decreased nonlinearly as increasing the Zr addition from 3% to 9% and M s decreased much more sharply as increasing the Zr addition. The M s of as-quenched Ti-18Nb-9Zr alloy was around room temperature. The effect of Zr addition on the β phase stabilizing in the Ti-18Nb(at.%) alloy was briefly discussed.
