Key words: Ni-based single crystal superalloy; Ru; stress rupture properties 1 Introduction The demand for developing an increasingly excellent comprehensive performance... in Fig. 1. It can be seen that the stress rupture life and elongation are increased with Ru addition. This indicates that addition of Ru to high refractory content Ni-based single crystal superalloy can......
CMSX-10, CMSX-11B and CMSX-11C all contain 0.1% Nb [18-19]. However, there is no research about the action of Nb in the Ni-based single crystal superalloy in open literature.In present work, the effect.... It indicates that the increase of Nb content to high refractory content Ni-based single crystal superalloy can decrease high temperature phase stability. The formation of TCP phases in Ni-based single crystal......
