Creep behavior of a directionally solidified nickel based superalloy

Directionally solidified nickel-base superalloys provide significant improvements relative to the limitations inherent to equiaxed materials in the areas of creep resistance, oxidation, and low and high cycle fatigue resistance. The objectives of this study are to perform critical experiments and investigate the high temperature creep deformation, creep rupture and creep crack growth behavior of DS GTD111. The specimens in the longitudinal …
