| Summary: | Titanium aluminide nano alloys has been
successfully produced by mechanical alloying (MA)
technique in a planetary ball mill and followed by
subsequent heating. The influence of milling
parameters such as the milling duration, rotation
speed and balls to powder mass ratio on the
characteristics of the Ti50%Al powder including
the micro structural, crystallite size refinement and
the phase formation were investigated. It was found
that mechanical alloying of elemental Ti and Al
powders has promotes the formation of Ti(Al) solid
solution with great crystallite size refinement.
Subsequent heating up to 850oC resulted in a
formation of new intermetallic with a dominant
TiAl3 phase. |
