Abstract
The injection molding process (MIM)for the Ti-15Mo-3Al alloys has been studied by using the mixed powder consisting of Ti.Mo and TiAl. The average size of these powders was 38 μm. 1.24μm and 9.4μm, respectively. The results obtained were as follows.
1) The kneading, molding and debinding (in the first stage)processes were successfully performed even in the air.
2) The compacts debound at 210°C in the air, followed by debinding at 500-550°C in a vacuum, were densified to a relative density of 97% or more after sintering for 3 hours at 1296°C in a high vacuum.
3) Many precipitated TiC partic]es were observed in these sintered compacts. which were not observed for the compacts obtained by conventional P/M process.
