Fabrication of Mo/Cu Functional Graded Material by Resistance Sintering under Ultra-High Pressure
A new resistance sintering method under ultra high pressure has been developed for fabrication of Mo/Cu (functional graded material) FGM. The consolidation was carried out under pressure of 8GPa, and input power of 15kW for 50s. The relative density of the FGM specimen was upwards 98% and the composition distribution was nearly the same as designed one. The micro-hardness and bend strength were measured to evaluate the sintering effects. The densification effect and microstructure of these FGM samples were investigated and the sintering mechanism was discussed.
