The present invention relates to a method of making an alloy of niobium comprising:
a) melting niobium to form a melt;
b) adding 0.1 to 60 ppm of a metal selected from the group consisting of yttrium, aluminum, hafnium, titanium, zirconium, thorium, lanthanum and cerium, based on the niobium in the melt;
c) cooling the melt to form an alloy ingot;
d) applying thermo-mechanical processing steps to the alloy ingot to form a wrought product. |
