Design of Low Youngs Modulus Ti Alloys Using d Electrons Alloy Thoery

摘要：

Ti-Nb-Zr ternary alloys with the low Youngs modulus were designed by d electrons alloy theory and were examined by experiments. The results showed that with the increase of Bo and Md of these alloys, the Youngs modulus decreased firstly and then increased. The decrease of Youngs modulus can be reasoned by the increase of the Md parameter which reflecting interatomic distance,and the increase of the Youngs moduli is correlated with the variability of phase structure from β phase to α phase. By defining the ratio of the Bo to Md as the effective Bo* , the decrease of the Youngs modulus can be explained qualitatively. The minimum Youngs modulus of these alloys was determined to be 36. 6 GPa,which is nearly the same with that of NiTi alloys.
