The corrosion resistant properties of tantalum, zirconium and titanium are reviewed and progress in process applications presented. Fabricating knowhow and industrial experience have progressed to the point that these metals can be accepted as reliable materials of construction. Additional fundamental research is needed, however, to understand the mechanisms of attack and passivity noted. The use of these metals can now be economically justified in many locations. Volume production and lower prices forecast for titanium and zirconium due to defense needs will lead to expanded use in corrosion resistant applications. 6.5
