N2 - In order to discuss the effect of content of primary α on properties of bimodal microstructure, the TC4 sheet in rolling state was heat treated at different temperatures of 10∼50°C below the β-transus temperature, then a series of bimodal microstructures with different content of primary α were obtained by air-cooled procedure. Quasi-static and dynamic compress tests were carried out with universal material testing machine and Split Hopkinson Pressure Bar (SHPB) respectively. The results indicated that the relationship between mechanical properties and primary α is irregular, and that bimodal microstructure with 25% primary α shows a better combination of strength and ductility.
