Abstract
The effect of heat treatment conditions on high rate mechanical properties of the ( $\alpha +\beta$) titanium alloy Ti-6Al-4V was investigated. Dependent on the solution annealing temperature, cooling rate and further annealing the strength and failure properties can be varied in a wide range. Microstructures obtained by annealing below the $\beta$-transus followed by furnace cooling show balanced properties of high strength, deformability, and therefore the highest energy consumption under dynamic compressive loading, but the lowest hardness values. Instrumented impact tests on Charpy U-notch specimens reveal evidence for a less brittle behaviour combined with the highest absorbed energy for furnace cooled conditions, only.
