Damping capacities of B19′ and B2 phases of this alloy are lower than those of Ti51Ni49 alloy due to Zr atoms solid-soluted hardening. Transformation temperatures of this alloy decrease, but transformation peak heights Qmax-1 increase with increasing aging time at 300 °C due to the formation of finer (0 0 1) M twins for specimens aged longer. The Qmax-1 peaks of the slightly cold-rolled Ti40.5Ni49.5Zr10 alloy are higher than those of the as-annealed alloy, which may be because the thinner twins are induced by small deformation. © 2005 Elsevier B.V.
