چکیده انگلیسی
By alloying and thermo-mechanical treatment, a novel low-cost metastable β-type Zr-4Mo-4Sn alloy was designed and fabricated for biomedical applications. Upon solution treatment plus quenching, the β-type Zr-4Mo-4Sn alloy exhibits a combination of low Young's modulus (48â¯GPa) and low magnetic susceptibility (1.22â¯Ãâ¯10â6â¯cm3â¯gâ1). This low magnetic susceptibility (Ï) is reasonably attributed to the choice of alloying components with low Ï, i.e., Zr (ÏZrâ¯=â¯1.32â¯Ãâ¯10â6â¯cm3â¯gâ1), Mo (ÏMoâ¯=â¯0.75â¯Ãâ¯10â6â¯cm3â¯gâ1) and Sn (ÏSnâ¯=â¯0.03â¯Ãâ¯10â6â¯cm3â¯gâ1). An analysis of single-crystal elastic constants and Hill approximation indicated that in comparison to binary β-type Ti-based alloys, the present β-type Zr-4Mo-4Sn alloy possesses lower bcc-structural (β-phase) stability represented by its lower Câ² and much lower C44, resulting in the ultralow Young's modulus of Zr-4Mo-4Sn alloy.
