摘要
Abstract
The graphene nanosheets were dispersed in the superalloy powder by using the wet mixing method,and then the nickel based FGH96 P/M superalloy was prepared with hot isostatic pressing (HIP) +hot extrusion(HEX) +hot isothermal forging(HIF) + heat treating(HT) processes.The results show that the graphene well disperses in the superalloy powder and keeps its original form during the following hot processing.After 0.1% (mass fraction) graphene is added,the average room temperature tensile strength and yield strength increase by 58MPa and 43MPa respectively,and the ductility increases from 21.0% to 37.3%;the tensile strength and yield strength at 650℃ increase by 58MPa and 28MPa,and the ductility increases from 18.5% to 26.5%.The mechanism of strengthening and toughening reinforcement was also analyzed based on graphene reinforced FGH96 superalloy.关键词
