Li Wen Liu Guifu(Changchun University, Changchun,130022)Kong Xiaohua(Changchun Institue of Applied Chemistry, Chinese Academy of Science)  
The valence electron structures, “average deforming factor” α and cleavage energy G c of Ti aluminides affected by alloying are calculated by BLD method of the empirical theory of solids and molecules(EET), and the alloying effects on the embrittlement of Ti aluminides are discussed on the basis of the calculated results. It indicates that Ti 3Al based alloys with the addition of macroalloyed Nb causes a partly disordered α 2 phase, incorporate the toughening phase while weakening the Ti Ti covalent bond, which increases α and G c and thus the embrittlement of Ti 3Al based alloys is basically improved. The addition of Mn in TiAl based alloys weakens the Al Al covalent bond and initiates the twinning, which makes α and G c somewhat enhanced and the embrittlement of TiAl based alloys is improved to some extent. Addition of Mn has no effect on the improvement of embrittlement of low TiAl 3 based alloys because of its very low α and G c values.
