1results about How to "Reduce crack propagation" patented technology

The application belongs to the technical field of alloy forging preparation, and particularly relates to a 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings. The 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings improves the strength of the forging matrix, reduces the crack propagation ability of the material, improves the crack propagation work of the material, and improves the toughness of the forging matrix. The 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings has high operability, improves the high-strength and high-toughness of the 05Cr17Ni4Cu4Nb sealing ring forging after heat deformation, cooling and direct aging.
