Crystallization Kinetics of an Amorphous TiAl Sheet Produced by PVD

Abstract

An amorphous, 150 micrometers thick freestanding sheet of a TiAl-based alloy was produced by a physical vapor deposition method. The following phase transformations were observed and analyzed using differential thermal analysis and X-ray diffraction, amorphous body centered cubic beta hexagonal close-packed alpha tetragonal gamma + ordered HCP alpha(sub 2).
