TEM specimens of PREPed Ti -48 at.% Al powders can be prepared reproducibly in a straight-forward manner. There are two kinds of powders with respect to surface and crosssectional morphologies. One is with an Widmanstitten-like structure and or a surface relief of martensitic phase and the other is with a dendritic structure. The primary phase during solidification and relative cooling rate in both the powders are discussed by comparing the macroscopic and microscopic features.
