Study on microstructure of multi-component micro-alloying TiAl-based alloy with high Nb content

WANG Yan-jing,SONG Mei-jin,WANG Ji-jie,DU Xing-hao(School of Material Science and Engineering,Shenyang Aerospace University,Shenyang 110136)  
The as-cast and heat-treated microstructure of B,Hf,Y micro-alloyed TiAl-based alloy with high Nb content were investigated.The OM observation shows that,the as-cast microstructure of B,Hf,Y micro-alloyed TiAl-based alloy was near lamellar microstructure in which α2/γ lamellar colonies were refined.The XRD analysis shows that,besides α2 and γ phase,β(B2),Y2O3,YAl2 were also included in the as-cast microstructure.The analysis of SEM combined with EDS shows that the β(B2) phase was distributed near the lamellar colonies grain boundaries,granular Y2O3 and YAl2,and granular or strip boride existed in grains and grain boundaries.After heat treatment at 1260℃ for 20h,at 900℃ for 30min and subsequent air-cooling,the duplex microstructures composed with thin α2/γ lamellar and γ equiaxed axis grains were obtained in the alloy,the β(B2) phase has been basically eliminated,simultaneously the YAl2 has disappeared,and meanwhile Hf-rich Y2O3 and Nb-rich titanium boride phases formed.
