Explanation
The conventional zircaloy-4 is a zirconium tin alloy composed of Zr-1.20~1.70, Sn-0.18~0.24, Fer0.07~0.13, and Cr (mass fraction.%). The alloy is made of ingots by vacuum consumable arc melting, and plastic forming is carried out by conventional pressure processing. It is mainly used as the cladding materials of pressurized water reactor and other core structural materials. The improved zircaloy-4 is a alloy after the composition adjustment and processing technology improvement of the conventional zircaloy-4 within the standard composition range. Its corrosion resistance and high-temperature performance are further improved.
