Binding and dispersion behavior of amorphous powders in diamond particles

Abstract This work was to prepare the diamond reinforced Cu 54 Ni 6 Zr 22 Ti 18 bulk metallic glass matrix composites using Spark Plasma Sintering (SPS) process. The effect of mixing methods such as mechanical alloying (MA), and turbula mixing–dry mixing (DM) and wet mixing (WM) on the uniformity of constituent phase was also investigated. Examination of microstructure and evaluation of mechanical properties of the composites were performed depending on the mixing processes. As a result, WM composite showed the highest mechanical properties. The experimental results indicated that the mixing method was essential parameter to determine the quality of MG/diamond composites such as the uniformity of phase and binding behavior.
