Zr alloys, Zr alloy products and Zr alloy parts

摘要

PROBLEM TO BE SOLVED: To provide a Zr alloy that has both strength and corrosion resistance and is less likely to cause artifacts in MRI imaging, that is, has a low magnetic susceptibility, a Zr alloy product using the same, and a Zr alloy part. A Zr alloy containing 3% or more and 12% or less of Ti, 3% or more and 18% or less of Nb, and 60% or more and 94% or less of Zr on a mass basis is used. Further, on a mass basis, it further contains at least one of Cr, Ni or Co of more than 0% and 3% or less, Fe of more than 0% and 4% or less, or Mo of more than 0% and 15% or less, and the balance is Zr and It may consist of inevitable impurities.
