Van Thyne, R J

A review is presented on the properties of zirconium and zirconium alloys and their possible applications in fields other than reactors, especially in the chemical processing industries. Resiatance to CC/sub 2/ corrosion at temperatures up to 930 deg F can be obtained by adding 0.5% each of copper and molybdenum to zirconium. Tin and aluminum additions to zirconium stabilize the high-strength alpha phase up to 1200 deg F. The properties of Zircaloys and Al- Zr and Sn-Zr alloys at 1200 deg F are tabulated. However, most uses outside the reactor field are limited to commercial zirconium containing 2% hafnium. The corrosion rates of zirconium by a large number of acids, alkalis, chlorides, etc., are tabulated. On the basis of its corrosion resistance, zirconium may replace stainless steel or titanium in some applications. The use of zirconium as a getter material for oxygen and in flashbulbs is discussed.
