| Abstract Scope |
Shear-Assisted Processing and Extrusion (ShAPE) is a solid phase processing technique that produces bulk size metal-matrix-composite (MMC) continuously without agglomeration. Void-free composite wires were directly produced in the single-step process. Two types of precursors were used: 1) a blend of copper carbon powder, 2) a solid copper cylinder with pre-drill holes filled with carbon powder. The measured processing temperature is below 600oC which is much lower than the melting temperature of copper. Energy Dispersive Spectroscopy (EDS) shows a highly homogenized carbon distribution with 50vol% carbon content. Electron backscatter diffraction (EBSD) indicates the grain size of the composite are refined from 78µm to 1µm. Differential scanning calorimetry (DSC) shows the composite has 22% higher specific heat capacity compared to copper. |
