| Abstract: | The creep, the stress rupture and the fatigue at 65 ℃, and theimpact and tensile properties from 20 ℃ to 800 ℃ of advanced Fe - based containing Nb superalloy GH871 by vacuum induction melting (VIM) + electroslag remelting (ESR) has been tested compared with that by atmosphere induction melting (AIM) + ESR. The results indicated that with melting by VIM + ESR, the stress elongation increased, and was more than 5%. |
