Abstract
A nickel base superalloy capable of being made into a single crystal article is provided with high temperature strength and improved stability by limiting the presence of an undesirable SRZ constituent. Significant to the control of formation of such undesirable constituents is the control of the amount of Re in the alloy in combination with elements such as Al, Cr, Ta, Mo, Co and W. A solution heat treatment is provided for additional control.
