Characterization of Ti–Al Intermetallic Synthesized by Mechanical Alloying Process

  • 33 Accesses


Mechanical alloying (MA) of Al60Ti40 (wt%) has been successfully done by using a planetary ball mill having mixed balls of 5 mm and 15 mm diameter to refine the crystallite size of the elemental powder and to get the new MAed phase of AlTi. The microstructural and morphological analysis of elemental as well as the processed powder was done with help of Scanning Electron Microscope and X-Ray diffraction technique. Mechanical alloying of elemental Al and Ti resulted in the formation of AlTi phases with the reflection of α-Ti3Al and TiAl3. The average particle size was reduced around 7 times after 60 h of milling. The mean crystallite size of MAed powder was also reduced up to 85 nm after 60 h of mechanical alloying under controlled conditions.
