Influence factors of ball milling process on BE powder for reaction sintering of TiB/Ti–4.0Fe–7.3Mo composite

A blended elemental (BE) route was used to mix, uniformly distributed FeMo and B or TiB2 particles into titanium powder by ball milling. The work presented here has demonstrated the influences of milling time, different powder mixture, process control agent (PCA), and size of milling ball and rotated speed on BE powder for reaction sintering of the TiB/Ti–4.0Fe–7.3Mo composite. The as milled powders were investigated by XRD analysis and SEM observation. The in situ reaction synthesized TiB reinforced Ti matrix composite has been successful prepared by ball milling and hot press sintering.
