Recently, Lee and researchers at Northwestern University did extensive work on Al[sub 3](M) dispersoids with a view of understanding their coarsening resistance. In particular, fcc L1[sub 2] and DO[sub 23]-structured Al[sub 3](M) phases showed slow coarsening kinetics, and thus L1[sub 2] and DO[sub 23] phases are believed to match the matrix better than the D0[sub 22] phase. However, most of the alloy compositions adopted in these works were confined within the range of the extents of solubility limits in binary aluminum alloys, from the viewpoint of rapid solidification processing. Therefore, in the present study, the authors investigated whether Al[sub 3]Ti dispersoids could be transformed to more stable phases by the addition of vanadium or zirconium as a third alloying element to Al-8wt.%Ti alloys, through the mechanical alloying process.
