Abstract
Transmission electron microscopy (TEM) and electron backseattered diffraction (EBSD) have been used to identify the crystal structures of long curvy and blocky borides which are formed at different cooling rates in TiAl based alloys. It has been found that for Ti 45A1 2Nb 2Mn 1 B the long curvy borides were either TiB borides with Bf structure or Ti 3B4 borides,and the blocky borides were either TiB borides with B27 struc ture or TiP^ borides. However,for Ti 48A1 2Cr 2Nb IB both long curvy borides and blocky borides were found to be TiB2borides. It is inferred that the crystal structures of borides are both composition and cooling rate related.
