Abstract Scope Rhenium (Tmelt=3186C) is unworkable HCP-metal due to its highest work-hardening. There is the problem with preparation of rhenium samples for mechanical testing. As a result, the deformation mechanisms in rhenium are still unknown. High pure polycrystalline rhenium after electron beam melting (EBM) was used in the work. The shift under pressure in Bridgeman’s anvils (SUP) was selected as deformation scheme for room temperature testing. SUP has shown that rhenium is able to severe deformation in spite of its huge work-hardening. Cracks appeared in EBM rhenium sheets under cold rolling, but their growth was powerfully braked. It means that there is considerable resource of plasticity in rhenium. The comparison of deformation behavior of rhenium with ruthenium allows concluding that the deformation mechanisms in rhenium are basal and prismatic slip as it was predicted from its “c/a” ratio. This research is supported by the Russian Science Foundation (#15-19-10007).
