There are 5 steps to make the niobium zirconium alloy 10 (niobium-zirconium, Nb-Zr 90/10 wt%).
Step 1: Take 9.5%-10.5% atomic energy level zirconium sponge and 89.5%-90.5% hydrogenation dehydrogenization niobium powder as per weight. Total percentage is 100%.
Step 2: Make the hydrogenation dehydrogenization niobium powder into electrode and purify it, then form niobium ingot in vacuum arc furnace.
Step 3: Remove the impurities from atomic energy level zirconium sponge, wash, vacuum dry and form the zirconium into ingot. Forge the ingot into zirconium sheet by hot rolling and cold rolling.
Step 4: Cut the zirconium sheet into strips at the same length as the niobium ingot in Step 2 Stick the zirconium strip tightly on niobium ingots and put them in vacuumed chamber filled with argon, get niobium zirconium compound ingot niobium-zirconium Nb-Zr 90/10 wt%.
Step 5: Melt the niobium zirconium compound ingot niobium-zirconium, Nb-Zr 90/10 wt% onto electrode, smelt the electrode in consumable electrode vacuum furnace for 5-6h, and cool with argon for 3.5-4h. Cut the alloy ingot into pieces, smelt for another 5-6h and argon cool for 3.5-4h. Finally get niobium-zirconium, Nb-Zr 90/10 wt%.
