英文摘要	In order to investigate the dynamic mechanical properties and deformation mechanism of 2195 Al-Li alloy as new quenched, the high strain rate tensile experiments were carried out by the split Hopkinson tension bar equipment. Experimental strain rate ranged from 1000 to 4500 s(-1), and the texture types and microstructure evolution of the alloy at different strain rates were analyzed by EBSD. The results show that strength and elongation of the alloy increase gradually with the increase of strain rate. When the strain rate reaches 4200 s(-1), the ultimate tensile strength and elongation reach 398 MPa and 63%, respectively. Compared with quasi-static tensile test, the elongation is significantly improved. According to the analysis of EBSD results, with the increase of strain rate, the proportion of small-angle grain boundaries and the average KAM increase at the same time. And the strength and volume fraction of Goss texture and S texture increase with the increase of strain rate. At high strain rate tension, not only the plastic deformation of soft-oriented grains is more sufficient, but also more coordinated deformation of hard-oriented grains can be initiated. Furthermore, the deformation mechanism at high strain rate tension was revealed.
