Behavior of a Grade 5 titanium alloy after high pressure torsion (HPT) and equal channel angular pressing (ECAP) under conditions of high-speed erosion was studied. Samples of the alloy in the ultrafine-grained state after the HPT and ECAP treatment were tested in an abrasive flow with various velocities using a technique similar to those presented in article Petrov et al. (2017). Two abrasive powders were used: with 109 and 230 μm average particle size. The tests were carried out at room temperature. Fracture surface parameters were studied for all tested specimens and fracture type (ratio of viscous and brittle fracture) was evaluated in each case. Additionally, surface roughness mass loss dependencies on particle flow velocity was investigated for both HPT and ECAP samples.
