Abstract
Official abstract text for this publication.
A heat-resistant alloy contains at least one element selected from a group consisting of Al, Ti, Ni, Cr, and Mo, O, and Y, and a ratio of a content of Y in terms of mass to a content of O in terms of mass is 0.5 or greater and 100 or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat-resistant alloy containing Y, wherein a content of Ni is 50.0 mass % or greater and 55.0 mass % or less, wherein a content of Cr is 17.0 mass % or greater and 21.0 mass % or less, wherein a content of Fe is 11.0 mass % or greater and 25.0 mass % or less, wherein a content of Mo is 2.8 mass % or greater and 3.3 mass % or less, wherein a content of Nb is 4.75 mass % or greater and 5.50 mass % or less, wherein a content of Al is 0.20 mass % or greater and 0.80 mass % or less, wherein a content of Ti is 0.65 mass % or greater and 1.15 mass % or less, wherein a content of 0 is 0.002 mass % or greater and 0.1 mass % or less, and wherein a ratio of a content of Y in terms of mass to a content of 0 in terms of mass is 3.9 or greater and 40 or less. 2. The heat-resistant alloy according to claim 1 , wherein the content of 0 is 0.005 mass % or greater and 0.02 mass % or less. 3. The heat-resistant alloy according to claim 1 , wherein the content of Y is 0.026 mass % or greater and 0.5 mass % or less. 4. The heat-resistant alloy according to claim 1 , wherein the ratio of the content of Y in terms of mass to the content of 0 in terms of mass is 5.2 or greater and 40 or less. 5. The heat-resistant alloy according to claim 1 , wherein at least part of Y is contained as yttria. 6. The heat-resistant alloy according to claim 1 , wherein a content of Cu is 0.3 mass % or less, wherein a content of Mn is 0.35 mass % or less, wherein a content of C is 0.08 mass % or less, wherein a content of Si is 0.35 mass % or less, and wherein balance is Fe. 7. A heat-resistant alloy powder containing the heat-resistant alloy according to claim 1 . 8. A heat-resistant alloy structural component containing the heat-resistant alloy according to claim 1 . 9. A manufacturing method of a heat-resistant alloy structural component comprising: forming heat-resistant alloy powder containing the heat-resistant alloy according to claim 1 using molten metal to which metal Y is added; and forming a structural component by shaping the heat-resistant alloy powder.
