Abstract
Official abstract text for this publication.
Provided is a biocompatible alloy having low magnetic susceptibility and excellent mechanical properties. The biocompatible alloy according to the present invention contains: Zr as a main component; Nb of not less than 0.1% by mass and not greater than 25% by mass; Mo of not less than 0.1% by mass and not greater than 25% by mass; and Ta of not less than 0.1% by mass and not greater than 25% by mass. A total content of Nb, Mo, and Ta in the biocompatible alloy is not less than 2% by mass and not greater than 50% by mass. The biocompatible alloy has a mass susceptibility of not greater than 1.50×10−6 cm3/g. The biocompatible alloy has a Young's Modulus of not greater than 100 GPa. Various biocompatible implants and medical devices can be manufactured from the biocompatible alloy.
