| Abstract: | Resistance sintering under ultra-high pressure was developed to fabricate Mo-Cu alloys containing copper of 25%-75% in volume fraction.Consolidation was carried out under pressures of 2-10 GPa and an input power of 15 kW for 65 s.The densification effect and mechanical properties of these Mo-Cu alloys were investigated.The results show that these composites have high density and their mechanical properties are well.It is concluded that resistance sintering under ultra-high pressure is one of the fabrication methods which can avoid inhomogeneous structure and abnormal grain growth. |
