Abstract:

A single crystal nickel-base superalloy article is disclosed wherein small additions of vanadium within the range of 0.4-0.8 by weight are combined with similar titanium levels, within the range of 0.0-1.0 by weight, to lower the gamma solvus temperature and simultaneously raise the incipient melting temperature of the article. As a result, the article exhibits an expanded heat treatment range that permits complete solutioning after casting without the danger of melting. Author
