| Sumario: | 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 microstructural change related to the decrease in applied shearing force is discussed. The structural observations indicate that the reason for the decrease in shearing force appears to be the slip of the sample on the lower plate because of MoS2 lubrication. The internal structure of the Cu/MoS2 samples appears to be interrupted midway through the consolidation process by dissipating the applied shearing force. In contrast, particle bonding and grain refinement occurred only on the sample surface, as for the friction process, and extended gradually to the inside of the sample when the shearing distance increased. We controlled the metal consolidation by compression shearing at room temperature by dispersing MoS2 into a Cu matrix. The shearing force appears to be more effective in metal consolidation by compression shearing at room temperature than the shearing distance. |
