Zirconium based alloy |
(57) A Zr based alloy with 7-15% by weight Nb and 0.5-3% by weight Al can be quenched
in water from 1000°C to largely retain beta phase. It is then deformable at room temperature
to produce martensite.
The alloy, which can be made in an electric arc furnace and forged at 900°C to destroy
the original solidification structure, is particularly suitable for structural components
and fuel elements of nuclear reactors.
