Role of MoS2 Addition in the Consolidation of Metal from Powder to Plate by the Compression Shearing Method at Room Temperature

We use a Cu/MoS2 composite to provide a new approach to control the consolidation of materials by compression–shearing at room temperature. Cu/MoS2 samples were formed under several shearing distances and the resulting microstructures were observed and compared with pure Cu samples. The microstructu...
