Abstract Scope |
The microstructure, mechanical and magnetic properties of Zr-xNb-4Sn alloys were investigated to obtain novel Zr-based alloy with low Young’s modulus and magnetic susceptibility for biomedical implants. After homogenization annealing, hot forging and solution annealing, Zr-8Nb-4Sn alloys was composed of β+α″ phase, β+α″ phase, β+ω phase, respectively. The temperature at which the α" and ω phase were transformed into β phase during the heating process is about 200℃, and the phase transformation temperature decreased with the increase of Nb element. Among all the Zr-xNb-4Sn alloys, Zr-9Nb-4Sn alloy has the lowest Young's modulus of 46.6 GPa and the low magnetic susceptibility of 1.294x10-6 cm3g-1, which has a good application prospect for biomedical applications. |
