Abstract
Mechanical alloying (MA) of powder mixtures of Ti-48 mol%Al was performed for various milling times by a planetary ball mill, and the MA powders were hot-pressed at relatively low heating temperatures of 673-873 K and pressures of 200-600 MPa. The influence of hot-press temperature and pressure on consolidation (densification, reactive synthesis, etc.) was investigated for the MA powders. In this experiment, some non-reactive Ti powders remained in the consolidated materials, but the optimum hot-press conditions for consolidation by reactive sintering are determined by the MA conditions (milling duration, etc.).
