Abstract
Official abstract text for this publication.
A high-strength Ni-base alloy having favorable corrosion resistance, high strength, and high ductility, around room temperature is provided. A high-strength Ni-base alloy includes: in % by mass, less than 0.01% of C, not more than 0.5% of Si, not more than 0.5% of Mn, 15 to 25% of Cr. 1.0 to 5.0% of Mo or Mo+0.5W, 0.2 to 0.8% of Al, 1.0 to 2.0% of Ti, 3.00 to 3.80% of Nb, not more than 30% of Fe, and 0.0007 to 0.010% of Mg; Ni; and impurities. A value represented by Mg/S is not less than 0.7, and an A value is not less than 0.015 and less than 0.027, the A value being represented by A value=Al/(Al+1.77(Ti−1.36C)+3.44(Nb−5.1C)).
First claim
Opening claim text (preview).
What is claimed is: 1. A Ni-base alloy consisting of: in % by mass, less than 0.01% of C, not more than 0.5% of Si, not more than 0.5% of Mn, 15 to 25% of Cr, 1.0 to 5.0% of Mo or Mo+0.5W, 0.2 to 0.8% of Al, 1.0 to 2.0% of Ti, 3.00 to 3.80% of Nb, not more than 30% of Fe, and 0.0007 to 0.010% of Mg; Ni; and impurities, wherein a value represented by Mg/S is not less than 0.7, and an A value is not less than 0.015 and less than 0.027, the A value being represented by: A value=Al/(Al+1.77(Ti−1.36C)+3.44(Nb−5.1C)); and a total of an area ratio of a region where a plate-like intermetallic compound exists alone and an area ratio of a region where a plate-like intermetallic compound phase and a γ phase exist in a lamellar manner, in a cross-sectional microstructure after age-hardening treatment, is not more than 12.5%. 2. The Ni-base alloy according to claim 1 , wherein the A value is 0.015 to 0.025. 3. The Ni-base alloy according to claim 1 , wherein the total of the area ratios is not more than 10.0%.
