The measurements results of the hugoniout elastic limit and spall strength of high strength (α+β) titanium alloy VT22 under shock-wave loading with a impactor velocity of 850± 30 m/s are presented. Experimental results on the decay of thedecay of the elastic precursor depending on the distance passed by the wave are described by a power-law dependence. New data on the spall strength of the VT22 alloy in the range of strain rates in a rarefaction wave have been obtained 104-106 s-1. Keywords: titanium alloy, shock waves, strength, interferometer.
