Background:
2
Zr-based alloys have been widely used as nuclear materials. However
enhancement of the resistance of particl
e radiation
the mechanical properties
and the corrosion resistance in alloys are still required.
Purpose:
2
The aim is to develop a new Zr-based nuclear material of excellent mechanical properties and corrosion resistance.
Methods:
2
DC magnetron sputtering method was applied to preparing ZrCuNb ternary amorphous films precipitated upon the pure zirconium substrate. The structure of ZrCuNb films was characterized using scanning electron microscopy
energy dispersive spectroscopy
X-ray diffraction
and high-resolution transmission electron microscope. Testing on mechanical properties such as tensile experiment was performed for both the ZrCuNb films/Zr substrate (the composite material) and the corresponding Zr metal plate. Corrosion resistance was studied using potentiodynamic polarization measurements.
Results:
2
It is found that full amorphous structure in films could be obtained microalloying Nb in ZrCu alloy
such as Zr

film does not have higher hardness or Young's modulus
however
the composite material possesses relatively high tensile strength and in particular obviously larger plastic-strain range. The enhancement is caused by the difference in initiation mechanism of cracks between the amorphous film and Zr substrate that they propagate along different orientations. Cracks in the substrate and film interfere with each other
leading to a delayed catastrophic rupture. In addition
the composite material has a stronger corrosion resistance.
Conclusion:
2
Zr metal plate coated with ZrCuNb amorphous film is a novel composite material with excellent mechanical properties and good corrosion resistance
which has a potential application in the nuclear engineering.
