【摘要】：采用濕混法將石墨烯納米片分散到高溫合金粉末中,并采用熱等靜壓+熱擠壓+等溫鍛造+熱處理的方法制備出FGH96鎳基粉末高溫合金。結(jié)果表明:石墨烯納米片在高溫合金中分散均勻,初步發(fā)現(xiàn)在后續(xù)的熱工藝過程中并未發(fā)生變性;添加0.1%(質(zhì)量分?jǐn)?shù))的石墨烯后,室溫抗拉強(qiáng)度和屈服強(qiáng)度分別提高了58MPa和43MPa,塑性從21.0%提高到37.3%;650℃條件下抗拉強(qiáng)度和屈服強(qiáng)度分別提高了58MPa和28MPa,塑性從18.5%提高到26.5%。此外對(duì)石墨烯增強(qiáng)FGH96鎳基高溫合金力學(xué)性能的作用機(jī)制也進(jìn)行了進(jìn)一步分析。
[Abstract]:The graphene nanoparticles were dispersed into the superalloy powder by wet mixing method, and the FGH96 nickel base superalloy was prepared by hot isostatic pressing and isothermal forging heat treatment.The results show that graphene nanoparticles are uniformly dispersed in the superalloy, and no denaturation occurs in the subsequent thermal process, and the addition of 0.1 (mass fraction) graphene,The tensile strength and yield strength at room temperature increased 58MPa and 43MPa, respectively. The tensile strength and yield strength increased from 21.0% to 37.3 鈩，
