The inherent internal friction (IF PT + IF I ) B2→B19 of cold-rolled and annealed Ti 50 Ni 50 alloy that exhibits B2 → B19 martensitic transformation is studied under isothermal conditions. The tan δ value of (IF PT + IF I ) B2→B19 is proportional to σ 0 /ν 1/2 and its damping mechanism is thus rela
