Zirconium was roll clad with nickel, monel, inconel, titanium, and
an 18-8 stainless steel. With the exception of titanium, all of these metals
formed compounds at the zirconium interface and the resulting bonds had
poor mechanical properties. The titanium-zirconium bond had good
strength and ductility and showed no tendency to crack during thermal
cycling.
Sandwich-type diffusion couples of zirconium with copper, molybdenum,
platinum, silver, and tantalum indicated that all of these metals
formed hard, brittle diffusion products with zirconium.
