摘要：
The Mo based alloys with minor Ti additive were fabricated by successive processes of simple ball-milling and low-temperature sintering. Different from traditional titanium oxides additive, the minor Ti additive will adsorb nearby oxygen impurities to form TiO2 or Ti8O15 during above process, thus purifying Mo matrix. The size of formed titanium oxides (approximately 540 nm) is also close to that reported in relevant literatures. What's more, the Ti additive could availably refine the Mo powder particles during ball-milling process and improve its sintering activity. While maintaining high densit (> 99%), the sintered Mo based alloys with minor Ti additive possess finer grain (13.17 mu m -* 4.44 mu m) and higher hardness (249 HV0.2 -* 332 HV0.2) compared with pure Mo.
