ZIRCONIUM ALLOY WITH TUNGSTEN AND NICKEL

摘要

A zirconium alloy including tin (Sn) in a range of greater than 0.005 wt.% to less than 1.0 wt.%, preferably with a lower limit greater than 0.1 wt.% to an upper limit of less than 0.7 wt.%, and most preferably with a lower limit of greater than 0.3 wt.% to an upper limit of less than 0.5 wt.%; iron (Fe) in a range of greater than 0.05 wt.% to less than about 1.0 wt.%, preferably with a lower limit of greater than 0.2 wt.% to an upper limit of greater than 0.5 wt.%, and most preferably with a lower limit of greater than 0.3 wt.% to an upper limit of less than 0.4 wt.%; chromium (Cr) in a range of greater than 0.02 wt.% to less than 1.0 wt.%, preferably with a lower limit of greater than 0.05 wt.% to an upper limit of less than 0.5 wt.%, and most preferably with a lower limit of greater than 0.1 wt.% to an upper limit of less than 0.2 wt.%; silicon in a range of greater than 50 to less than 300 parts per million (ppm), preferably in a range of greater than 70 to about 200 ppm, and most preferably in a range of greater than 90 to about 150 ppm; tungsten (W) in a range of greater than 0.01 wt.% to less than 1.0 wt.%, preferably with a lower limit of greater than 0.1 wt.% to an upper limit of less than 0.7 wt.%, and most preferably with a lower limit of greater than 0.2 wt.% to an upper limit of about less than 0.5 wt.%; nickel (Ni) in a range of greater than 0.007 wt.% and less than about 0.3 wt.%, preferably with a lower limit of greater than 0.05 wt.% to an upper limit of less than about 0.2 wt.%, and most preferably with a lower limit of greater than 0.08 wt.% to an upper limit of less than about 0.1 wt.%, with the balance zirconium.
