摘要：
The α lamellar microstructures with different thicknesses were obtained by proper heat treatments of TC4 ELI alloy. The influence of α lamellar thickness on the dynamic mechanical properties of the material and its sensitivity to adiabatic shear banding was investigated. The split Hopkinson pressure bar and the stop ring technique are used to test the samples under strain controlled loading. The microstructure evolution is analyzed by microscope and quantitative metallography method. The experimental results demonstrate that the thickness of titanium alloy with lamellar structure decreases from 3.1 μm to 1.0 μm with the increase in solid solution temperature. Under the quasi-static compression and dynamic compression conditions, the material strength decreases as the thickness of lamellar α increases, while its plasticity exhibits a declining trend. In the adiabatic shear sensitivity experiment, the adiabatic shear bands are more likely to nucleate and propagate in the alloy with smaller lamellar thickness, that is, as the thickness of the lamella decreases, the adiabatic shear sensitivity of the material increases. © 2020, Editorial Board of Acta Armamentarii.
