Title:
Ni-BASED HEAT-RESISTANT ALLOY
Document Type and Number:
WIPO Patent Application WO/2018/116797
Kind Code:
A1
Abstract:
The present invention relates to a Ni-based heat-resistant alloy that comprises 5.0–50.0 mass% of Ir, 1.0–8.0 mass% of Al, and 5.0–25.0 mass% of W, the remainder being Ni, and that has, in a matrix, γ' phases that have an L12 structure, the Ni-based heat-resistant alloy being characterized by including 0.8–5.0 mass% of Ru and/or 0.8–5.0 mass% of Re. As compared to Ni-based heat-resistant alloys that are based on conventional Ni-Ir-Al-W alloys, this Ni-based heat-resistant alloy has improved toughness and excellent room temperature strength.
