| Abstract: | The development of HIP diffusion bonding of FGH95 superalloy powder and DD3 single crystal has been explored.The effects of HIP bonding temperature and heat treatment on element diffusion and precipitation at FGH95-DD3 interface have been discussed.The variations of microstrueture and mechanical properties of DD3 single crystal after hipping have also been investigated.The results show that perfect diffusion and bonding at powder-crystal interface can be achieved by proper process control,the properties of DD3 single crystal can alsobe maintained up to the desired levels after HIP diffusion bonding |
