Microstructure and Properties of Molybdenumprinciple-Copper Composite Metal Samples Consolidated by Plasma Pressure Compaction
In this study, a composite metal powder mixture using molybdenum and copper powders was consolidated tonear theoretical density using the rapid consolidation technique of plasma pressure compaction. Rapid consolidation of the mixture of metal powders is an essential requirement for better microstructural control and mechanical properties in the consolidated product. The microstructure and hardness of the composite samples are compared with monolithic samples made by consolidating pure molybdenum powders under identical conditions. Microhardness measurements revealed an increase in hardness of molybdenum when mixed with small amounts of copper. The role of consolidation parameters on hardness and microstructural development is presented and discussed.
