The influence of various alloy elements on tensile strength of the eutectic, directionally solidified superalloy 73 C was determined. The tensile properties of the base alloy had been increased by Al, Y and C as alloying elements, while Ni and Ti showed a decreasing effect (alloy softening). However, ductility and thermo‐fatigue behaviour had been influenced in a positive way be these elements. The specific mechanisms caused by the different elements are discussed.
