專利摘要(英)
The present invention discloses a low modulus corrosion-resistant alloy comprising five principal elements, wherein the five principal elements are Zr, Nb, Ti, Mo, and Sn. According to the present invention, these kind low modulus corrosion-resistant alloy contained: Zr more than 31 wt％, 18~50 wt％ Nb, 10~40 wt％ Ti, 4~10 wt％ Mo, and 1.5~15 wt％ Sn, wherein a summation of Zr and Ti in weight percent is less than or equal to 80. Experimental data reveal that, samples of the low modulus corrosion-resistant alloy includes following characteristics: hardness of at least 250 HV, Young’s modulus less than 100 GPa, yield strength greater than 600 MPa, and critical pitting potential greater than 1.3V. As a result, experimental data have proved that the low modulus corrosion-resistant alloy has a significant potential for application in manufacture of medical devices and surgical implants. Furthermore, the low modulus corrosion-resistant alloys are suitable in applications including springs, coils, wires, clamps, fasteners, blades, valves, elastic sheets, spectacle frames, sports equipment, and high-strength low-modulus corrosion-resistant structural material.
