Description
Technical Field

Background
The UNS N09925 alloy is a novel high-strength high-temperature corrosion-resistant alloy developed in recent years, and related research reports at home and abroad are few at present. The UNS N09925 alloy is a Fe-Ni-Cr high-temperature corrosion-resistant alloy which is prepared by properly increasing the contents of Fe and Cr to reduce the content of rare metal nickel on the basis of a nickel-based alloy. Because the alloy components are complex, the corresponding precipitated phases are increased, and higher requirements are put forward on the metallurgy technology and the heat treatment system. Compared with GH4169 nickel-based high-temperature corrosion-resistant alloy, the alloy has the advantages of low nickel content, high toughness, corrosion resistance, easy cutting and the like, has super-excellent alloy performance, can maintain high-temperature and excellent mechanical properties such as fatigue resistance and the like at high temperature, has oxidation resistance and corrosion resistance, and has good plasticity and weldability, and the UNS N09925 alloy is widely concerned at home and abroad.
The UNS N09925 alloy is an aging strengthening type alloy which takes an austenite gamma phase as a matrix and takes intermetallic compounds gamma '[ Ni3(Ti, Al) ] and gamma' [ Ni3(Nb, Ti, Al) ] as strengthening phases, and by adding trace precipitation strengthening elements such as Mo, Cu, Nb, Ti, Al and the like, excellent mechanical, high-temperature resistant and corrosion resistant properties are obtained. Intermetallic compounds γ' and γ ″ have a better strengthening effect than carbides; certain amounts of Mo, Cu, Ti and Al enable the strength and the corrosion resistance of the alloy to be perfectly combined. Sufficient Ni has good effect on resisting stress corrosion cracking caused by a medium containing chloride ions; the addition of Mo and Cu ensures that the alloy has good corrosion resistance in a reducing medium; mo is beneficial to improving the pitting corrosion resistance and the crevice corrosion resistance; cr can greatly improve the high-temperature oxidation resistance of the alloy. The addition of Ti and Al enriches the aging strengthening means of the alloy. The alloy is widely applied to the fields of oil and gas drilling equipment, chemical industry, ocean and the like with higher requirements on comprehensive properties of toughness, heat resistance, corrosion resistance and the like of materials.
