Title:

DYSPROSIUM-RICH NICKEL-TUNGSTEN ALLOY MATERIAL FOR NUCLEAR SHIELDING AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2024/045939

Kind Code:

A1

Abstract:

The present application relates to a dysprosium-rich nickel-tungsten alloy material for nuclear shielding, the composition thereof comprising components of the following mass percentages: C: 0.002-0.02%, W: 5.0-35.0%, Cr: 15.0-30.0%, Dy: 1.0-4.0%, and the remaining components are nickel and unavoidable impurities. A preparation method for the dysprosium-rich nickel-tungsten alloy material for nuclear shielding is also provided. In the present application, a high-dysprosium and high-tungsten nickel-tungsten alloy material is prepared by adding an appropriate ratio of nickel, chromium, tungsten and dysprosium, and has the advantages of high strength, good plasticity and toughness, corrosion resistance and excellent processing and formability, and can be used as an integrated material of a neutron and photon synergistic shielding functional structure.
