Abstract
A method of repairing an article includes removing an undesirable section of the article, attaching a repair section to the article at a location from which the undesirable section has been removed, and mechanically working the repair section to achieve a reduction in a cross-sectional area of the repair section.
Claims24
A method of repairing an article, comprising:
- removing an undesirable section of an article comprised of a metallic alloy;
- attaching a repair section to the article at a location from which the undesirable section has been removed, wherein the repair section is formed by depositing a powder on the article;
- and
- mechanically working the repair section subsequent to the attaching step to thereby achieve a reduction in a cross-sectional area of the repair section by 10%-50%, wherein mechanically working the repair section includes plastically deforming the repair section entirely through a repair section, wherein the repair section is substantially free from orthorhombic delta phase regions of Ni3Cb.

A method of repairing an article, comprising:
- removing an undesirable section of an article comprised of a metallic alloy;
- welding a repair section to the article at a location from which the undesirable section has been removed, wherein the repair section is formed by depositing a powder on the article;
- and
- mechanically cold working the repair section subsequent to the welding step at a temperature below a heat treating temperature of the metallic alloy to reduce a cross-sectional area of the repair section by 10%-50%, wherein the repair section is substantially free from orthorhombic delta phase regions of Ni3Cb.
