Hot-Press Sintering of the W-4Owt.%Cu Composite Tape-Casting Film

摘要：

　　In this research, the W-40wt.%Cu composite tape-casting films were prepared through the vacuum hot-press sintering method, and the effect of sintering temperature on the microstructures and properties of the W-40wt.%Cu composite samples was studied.Microstructures of the W-40wt.%Cu tape-casting film and the prepared samples were analyzed by field emission scanning electron microscopy (FE-SEM).The phase of the samples was investigated by X-ray diffraction (XRD).The relative density, Vickers hardness, bending strength and electrical conductivity of the samples were investigated.The results show that the relative density of the W-40wt.%Cu composite materials enhances with the increasing of the sintering temperature, at the same time the mechanical and electrical properties are better with the increasing of the sintering temperature.The W-40wt.%Cu composites prepared at the condition of 900℃-200MPa-2h have the relative density of 97%, the bending strength of 507.3MPa, the Vickers hardness of 376.2HV and the electrical conductivity of 32.5% IACS, respectively.
