| By using fast replication, honeycomb strutting piece were fabricated which have different apertures and wall thicknesses, the liquidity of slurry-casting and solidification and dewaxing technologies and powder sintring technologies were investigated. By means of metallographic microscope, X-ray diffraction(XRD), scanning electron microscope, energy dispersive X-ray spectroscope(EDX), microstructure and phase composition of honeycombs were investigated respectively. The test of mechanical property of honeycombs are carried on using compression tester. The changes of the yield strength and the Young's modulus was obtained.The Ti honeycomb and superalloy honeycomb was fabricated by using optimizational fast replication craft and powder sintering craft. The maximum porosity of honeycomb which were fabricated can achieve 90%. The aperture and wall thickness of honeycomb can control strictly by using fast replication. The honeycombs which were fabricated have good shape, the technologies which was used in this paper is feasibility.It was found that there was a small amount of Ti particles in theα-Ti by XRD and EDS. Ti honeycomb has good resist compression property, the yield strength and the Young's modulus decrease with reducing of relative density. The value of yield strength decreases from 205.5MPa to 7 MPa and the value of Young's modulus decreases from 3.1GPa to 0.4GPa when the value of relative density decrease form 39% to 9%.Energy dispersive X-ray spectroscope and X-ray diffraction analysis for Inconel 617 superalloy honeycomb indicated that the microstructures areγphase and M23C6 carbide. The mechanical property of Inconel 617 superalloy honeycomb was investigated. The value of yield strength decreases from 56.1MPa to 54.6MPa and the value of Young's modulus decreases from 2.9GPa to 1.2GPa when the value of relative density decrease form 24.4% to 14.8%. Sintering property of the fine powders was better than those of coarse powders.
