Oxide particle dispersion strengthened Ni-base superalloy

摘要

Along with Ni, it contains 0.1% by mass or more and 14.0% by mass or less of Ru, 0.1% by mass or more and 14.0% by mass or less of Al, and unavoidable impurities. It is assumed that oxide particles of not less than mass% and not more than 3.0 mass% are dispersed.
