| Abstract: | The development of HIP diffusion bonding of P/M superalloy FGH95 powder and K418B cast blade materials has been explored.The effects of HIP bonding process on elements diffusion and precipitation at FGH95-K418B interface were discussed.The variations of microstructure and mechanical properties of K418B cast blade materials after hipping have also been investigated.The results show that the perfect diffusion and bonding at powder-blade materials interface can be achieved by proper control,and the properties ... |
