The influence of cooling rate and alloy composition on the formation of borides during solidification of boron-containing TiAl alloys

, 2012
It has been found that for Ti-45Al-2Nb-2Mn-1B the long curvy borides were either TiB borides with Bf structure or Ti3B4 borides, and the blocky borides were either TiB borides with B27 structure or TiB2 borides.
