In this work the effect of crystal structure perfection on the creep resistance of single crystal superalloys. The CMSX-4 and CMSX-4®Plus with increased Re content is analyzed. Single crystal rods are made by directional solidification process at the withdrawal rates 3 and 5 mm/min. The evaluation of microstructure and crystal structure perfection are carried out by light microscopy and X-ray diffraction Ω-scan methods. Creep tests are performed according to ASTM E-139-11 standard at the temperature of 982°C. Mathematical models for the creep resistance of the models are developed for both investigated superalloys. The influence of the crystal structure on the the investigated superalloys are built and the steady state creep rates are determined. Creep strength of both superalloys are compared. The results show that the CMSX-4®Plus nickel superalloy exhibits nearly two times higher creep resistance compared to the conventional CMSX-4 one.
